The Ohio River is a 981-mile long river in the midwestern United States that flows southwesterly from western Pennsylvania south of Lake Erie to its mouth on the Mississippi River at the southern tip of Illinois. It is the second largest river by discharge volume in the United States and the largest tributary by volume of the north-south flowing Mississippi River that divides the eastern from western United States; the river flows through or along the border of six states, its drainage basin includes parts of 15 states. Through its largest tributary, the Tennessee River, the basin includes several states of the southeastern U. S, it is the source of drinking water for three million people. The lower Ohio River just below Louisville is obstructed by rapids known as the Falls of the Ohio where the water level falls 26ft. in 2 miles and is impassible for navigation. The McAlpine Locks and Dam, a shipping canal bypassing the rapids, now allows commercial navigation from the Forks of the Ohio at Pittsburgh to the Port of New Orleans at the mouth of the Mississippi on the Gulf of Mexico.
The name "Ohio" comes from the Ohi: yo', lit. "Good River". Discovery of the Ohio River may be attributed to English explorers from Virginia in the latter half of the 17th century. In his Notes on the State of Virginia published in 1781–82, Thomas Jefferson stated: "The Ohio is the most beautiful river on earth, its current gentle, waters clear, bosom smooth and unbroken by rocks and rapids, a single instance only excepted." In the late 18th century, the river was the southern boundary of the Northwest Territory. It became a primary transportation route for pioneers during the westward expansion of the early U. S; the river is sometimes considered as the western extension of the Mason–Dixon Line that divided Pennsylvania from Maryland, thus part of the border between free and slave territory, between the Northern and Southern United States or Upper South. Where the river was narrow, it was the way to freedom for thousands of slaves escaping to the North, many helped by free blacks and whites of the Underground Railroad resistance movement.
The Ohio River is a climatic transition area, as its water runs along the periphery of the humid subtropical and humid continental climate areas. It is inhabited by flora of both climates. In winter, it freezes over at Pittsburgh but farther south toward Cincinnati and Louisville. At Paducah, Kentucky, in the south, near the Ohio's confluence with the Mississippi, it is ice-free year-round; the name "Ohio" comes from the Seneca language, Ohi:yo', a proper name derived from ohiːyoːh, therefore translating to "Good River". "Great river" and "large creek" have been given as translations. Native Americans, including the Lenni Lenape and Iroquois, considered the Ohio and Allegheny rivers as the same, as is suggested by a New York State road sign on Interstate 86 that refers to the Allegheny River as Ohi:yo'. An earlier Miami-Illinois language name was applied to the Ohio River, Mosopeleacipi. Shortened in the Shawnee language to pelewa thiipi, spelewathiipi or peleewa thiipiiki, the name evolved through variant forms such as "Polesipi", "Peleson", "Pele Sipi" and "Pere Sipi", stabilized to the variant spellings "Pelisipi", "Pelisippi" and "Pellissippi".
Applied just to the Ohio River, the "Pelisipi" name was variously applied back and forth between the Ohio River and the Clinch River in Virginia and Tennessee. In his original draft of the Land Ordinance of 1784, Thomas Jefferson proposed a new state called "Pelisipia", to the south of the Ohio River, which would have included parts of present-day Eastern Kentucky and West Virginia; the river had great significance in the history of the Native Americans, as numerous civilizations formed along its valley. For thousands of years, Native Americans used the river as a major trading route, its waters connected communities. In the five centuries before European conquest, the Mississippian culture built numerous regional chiefdoms and major earthwork mounds in the Ohio Valley, such as Angel Mounds near Evansville, Indiana, as well as in the Mississippi Valley and the Southeast; the Osage, Omaha and Kaw lived in the Ohio Valley, but under pressure from the Iroquois to the northeast, migrated west of the Mississippi River in the 17th century to territory now defined as Missouri and Oklahoma.
The discovery and traversal of the Ohio River by Europeans admits of several possibilities, all in the latter half of the 17th century. Virginian Englishman Abraham Wood's trans-Appalachian expeditions between 1654 and 1664; the first person to traverse the length of the river, from the headwaters of the Allegheny to its mouth on the Mississippi, was a Dutch trader from New York, Arnout Viele, in 1692. In 1749, Great Britain established the Ohio Company to trade in the area. Exploration of the territory and trade with the Indians in the region near the Forks brought British colonials from both Pennsylvania and Virginia across the mountains, both colonies claimed the territory; the movement across the Allegheny Mountains of British settlers and the claims of the area near modern day Pittsburgh led to conflict with the French, who had forts in the Ohio River Valley. This conflict was called the Indian War. In 17
Kentucky the Commonwealth of Kentucky, is a state located in the east south-central region of the United States. Although styled as the "State of Kentucky" in the law creating it, Kentucky is one of four U. S. states constituted as a commonwealth. A part of Virginia, in 1792 Kentucky became the 15th state to join the Union. Kentucky is the 26th most populous of the 50 United States. Kentucky is known as the "Bluegrass State", a nickname based on the bluegrass found in many of its pastures due to the fertile soil. One of the major regions in Kentucky is the Bluegrass Region in central Kentucky, which houses two of its major cities and Lexington, it is a land with diverse environments and abundant resources, including the world's longest cave system, Mammoth Cave National Park, the greatest length of navigable waterways and streams in the contiguous United States, the two largest man-made lakes east of the Mississippi River. Kentucky is known for horse racing, bourbon distilleries, coal, the "My Old Kentucky Home" historic state park, automobile manufacturing, bluegrass music, college basketball, Kentucky Fried Chicken.
In 1776, the counties of Virginia beyond the Appalachian Mountains became known as Kentucky County, named for the Kentucky River. The precise etymology of the name is uncertain, but based on an Iroquoian name meaning " the meadow" or " the prairie". Others have put forth the possibility of Kenta Aki, which would come from Algonquian language and, would have derived from the Shawnees. Folk etymology states that this translates as "Land of Our Fathers." The closest approximation in another Algonquian language, Ojibwe translates it more-so to "Land of Our In-Laws", thus making a fairer English translation "The Land of Those Who Became Our Fathers." In any case, the word aki comes out as land in all Algonquian languages. Kentucky is situated in the Upland South. A significant portion of eastern Kentucky is part of Appalachia. Kentucky borders seven states, from the Southeast. West Virginia lies to the east, Virginia to the southeast, Tennessee to the south, Missouri to the west and Indiana to the northwest, Ohio to the north and northeast.
Only Missouri and Tennessee, both of which border eight states, touch more. Kentucky's northern border is formed by the Ohio River and its western border by the Mississippi River. However, the official border is based on the courses of the rivers as they existed when Kentucky became a state in 1792. For instance, northbound travelers on U. S. 41 from Henderson, after crossing the Ohio River, will be in Kentucky for about two miles. Ellis Park, a thoroughbred racetrack, is located in this small piece of Kentucky. Waterworks Road is part of the only land border between Kentucky. Kentucky has a non-contiguous part known at the far west corner of the state, it exists as an exclave surrounded by Missouri and Tennessee, is included in the boundaries of Fulton County. Road access to this small part of Kentucky on the Mississippi River requires a trip through Tennessee; the epicenter of the powerful 1811–12 New Madrid earthquakes was near this area causing the river to flow backwards in some places. Though the series of quakes did change the area geologically and affect the inhabitants of the area at the time, the Kentucky Bend was formed because of a surveying error, not the New Madrid earthquake.
Kentucky can be divided into five primary regions: the Cumberland Plateau in the east, the north-central Bluegrass region, the south-central and western Pennyroyal Plateau, the Western Coal Fields and the far-west Jackson Purchase. The Bluegrass region is divided into two regions, the Inner Bluegrass—the encircling 90 miles around Lexington—and the Outer Bluegrass—the region that contains most of the northern portion of the state, above the Knobs. Much of the outer Bluegrass is in the Eden Shale Hills area, made up of short and narrow hills; the Jackson Purchase and western Pennyrile are home to several bald cypress/tupelo swamps. Located within the southeastern interior portion of North America, Kentucky has a climate that can best be described as a humid subtropical climate, only small higher areas of the southeast of the state has an oceanic climate influenced by the Appalachians. Temperatures in Kentucky range from daytime summer highs of 87 °F to the winter low of 23 °F; the average precipitation is 46 inches a year.
Kentucky experiences four distinct seasons, with substantial variations in the severity of summer and winter. The highest recorded temperature was 114 °F at Greensburg on July 28, 1930 while the lowest recorded temperature was −37 °F at Shelbyville on January 19, 1994, it has four distinct seasons, but experiences the extreme cold as far northern states, nor the high heat of the states in the Deep South. Temperatures seldom drop below 0 degrees or rise above 100 degrees. Rain and snowfall totals about 45 inches per year. There are big variations in climate within the state; the northern parts tend to be about 5 degrees cooler than those in western parts of the state. Somerset in the south-central part receives 10 more inches of rain per year than, for instance, Covington to the north. Average temperatures for the entire Commonwe
The Shawneetown Bridge is a cantilever truss bridge carrying Kentucky Route 56 and Illinois Route 13 across the Ohio River. The bridge connects Old Illinois to rural Union County, Kentucky. Opened in 1955, it is the only highway bridge over the Ohio between Evansville; the Shawneetown Bridge was featured in a scene in the film U. S. Marshals; the film's crash scene was filmed several miles downstream in Illinois. Historic Bridges of the U. S. - Shawneetown Bridge
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements forming triangular units. The connected elements may be stressed from tension, compression, or sometimes both in response to dynamic loads. Truss bridges are one of the oldest types of modern bridges; the basic types of truss bridges shown in this article have simple designs which could be analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct; the nature of a truss allows the analysis of its structure using a few assumptions and the application of Newton's laws of motion according to the branch of physics known as statics. For purposes of analysis, trusses are assumed to be pin jointed; this assumption means that members of the truss will act only in compression. A more complex analysis is required where rigid joints impose significant bending loads upon the elements, as in a Vierendeel truss. In the bridge illustrated in the infobox at the top, vertical members are in tension, lower horizontal members in tension and bending, outer diagonal and top members are in compression, while the inner diagonals are in tension.
The central vertical member stabilizes the upper compression member. If the top member is sufficiently stiff this vertical element may be eliminated. If the lower chord is sufficiently resistant to bending and shear, the outer vertical elements may be eliminated, but with additional strength added to other members in compensation; the ability to distribute the forces in various ways has led to a large variety of truss bridge types. Some types may be more advantageous when wood is employed for compression elements while other types may be easier to erect in particular site conditions, or when the balance between labor and material costs have certain favorable proportions; the inclusion of the elements shown is an engineering decision based upon economics, being a balance between the costs of raw materials, off-site fabrication, component transportation, on-site erection, the availability of machinery and the cost of labor. In other cases the appearance of the structure may take on greater importance and so influence the design decisions beyond mere matters of economics.
Modern materials such as prestressed concrete and fabrication methods, such as automated welding, the changing price of steel relative to that of labor have influenced the design of modern bridges. A pure truss can be represented as a pin-jointed structure, one where the only forces on the truss members are tension or compression, not bending; this is used by the building of model bridges from spaghetti. Spaghetti is brittle and although it can carry a modest tension force, it breaks if bent. A model spaghetti bridge thus demonstrates the use of a truss structure to produce a usefully strong complete structure from individually weak elements; because wood was in abundance, early truss bridges would use fitted timbers for members taking compression and iron rods for tension members constructed as a covered bridge to protect the structure. In 1820 a simple form of truss, Town's lattice truss, was patented, had the advantage of requiring neither high labor skills nor much metal. Few iron truss bridges were built in the United States before 1850.
Truss bridges became a common type of bridge built from the 1870s through the 1930s. Examples of these bridges still remain across the US, but their numbers are dropping as they are demolished and replaced with new structures; as metal started to replace timber, wrought iron bridges in the US started being built on a large scale in the 1870s. Bowstring truss bridges were a common truss design during this time, with their arched top chords. Companies like the Massillon Bridge Company of Massillon and the King Bridge Company of Cleveland, Ohio became well-known, as they marketed their designs to cities and townships; the bowstring truss design fell out of favor due to a lack of durability, gave way to the Pratt truss design, stronger. Again, the bridge companies marketed their designs, with the Wrought Iron Bridge Company in the lead; as the 1880s and 1890s progressed, steel began to replace wrought iron as the preferred material. Other truss designs were used during this time, including the camel-back.
By the 1910s, many states developed standard plan truss bridges, including steel Warren pony truss bridges. As the 1920s and 1930s progressed, some states, such as Pennsylvania, continued to build steel truss bridges, including massive steel through-truss bridges for long spans. Other states, such as Michigan, used standard plan concrete girder and beam bridges, only a limited number of truss bridges were built; the truss may carry its roadbed in the middle, or at the bottom of the truss. Bridges with the roadbed at the top or the bottom are the most common as this allows both the top and bottom to be stiffened, forming a box truss; when the roadbed is atop the truss it is called a deck truss. When the truss members are both above and below the roadbed it is called a through truss, where the sides extend above the roadbed but are not connected, a pony truss or half-through truss. Sometimes both the upper and lower chords support roadbeds; this can be used to separate rail from road traffic or to separate the two directions of automobile traffic and so avoiding the likelihood of head-on c
Irvin S. Cobb
Irvin Shrewsbury Cobb was an American author, humorist and columnist from Paducah, who relocated to New York in 1904, living there for the remainder of his life. He wrote for the New York World, Joseph Pulitzer's newspaper, as the highest paid staff reporter in the United States. Cobb wrote more than 60 books and 300 short stories; some of his works were adapted for silent movies. Several of his Judge Priest short stories were adapted in the 1930s for two feature films directed by John Ford. Cobb was the second of four children born to Kentucky natives in Kentucky, his maternal grandfather, Reuben Saunders, M. D. is credited with discovering in 1873 that hypodermic use of morphine-atropine halted cholera. Cobb was raised in Paducah, the events and people of his childhood became the basis for much of his works. In life, Cobb was nicknamed "Duke of Paducah."Cobb was educated in public and private elementary schools, entered William A. Cade's Academy intending to pursue a law career; when Cobb was 16, his father became an alcoholic, after the death of his grandfather.
Forced to quit school and find work, Cobb began his writing career. Cobb started in journalism with the Paducah Daily News at age seventeen, became the nation's youngest managing news editor at age nineteen, he worked at the Louisville Evening Post for a year and a half. His anecdotal memoir-cum-autobiography, Exit Laughing, published in 1941, includes a firsthand account of the assassination of Kentucky Governor William Goebel in 1900 and the trials of the killers, he wrote numerous series in periodicals, collaborated on dramatic productions. After moving to New York in 1904, Cobb was hired by the Evening Sun; the publication sent him to Portsmouth, New Hampshire to cover the Russian-Japanese peace conference. His dispatches from the negotiations, emphasizing the personalities involved, were published across the country with the title "Making Peace at Portsmouth." They earned him a job offer from Joseph Pulitzer's New York World and he became the highest-paid staff reporter in the United States.
Cobb joined the staff of the magazine The Saturday Evening Post in 1911, covered the Great War for the magazine. At the same time, he wrote. After a second visit to France to cover the Great War, Cobb publicized the achievements of the unit known as the Harlem Hellfighters, most notably, Croix de Guerre recipients Henry Johnson and Needham Roberts, his article "Young Black Joe," published on August 24, 1918, in The Saturday Evening Post and republished in Cobb's book, The Glory of the Coming, highlighted the discipline and courage displayed by black American soldiers fighting in Europe during World War I. The three-page article and half-page photograph reached a national audience of more than two million readers, was reprinted in the black press. In the midst of covering the 1920 Democratic Convention, Cobb received 1.5 votes on the 23rd Presidential ballot. Several of Cobb's stories were adapted as silent movies, he wrote the screen titles for other movies, including the Jackie Coogan movie, Peck's Bad Boy.
With the advent of sound, more of his stories were adapted for the screen, including The Woman Accused, featuring young Cary Grant. John Ford twice made movies based on Cobb's Judge Priest stories: Judge Priest featured Will Rogers in the title role; the Sun Shines Bright was based on his short stories "The Sun Shines Bright", "The Mob from Massac", "The Lord Provides". Cobb had an acting career, acting in ten movies between 1932 and 1938, he won major roles in such movies as Pepper, Everybody's Old Man, Hawaii Calls. He was host of the 7th Academy Awards in 1935. In 1919, Cobb was recruited by former U. S. Navy officer and lawyer Capt. W. H. Slayton to become chairman of the Authors and Artists Committee of the Association Against the Prohibition Amendment; the Association based their opposition on the misuse of national government power over U. S. citizens. As chairman, Cobb helped extend coverage of their message through the media and artist networks. "If Prohibition is a noble experiment," he said in one, "then the San Francisco fire and the Galveston flood should be listed among the noble experiments of our national history."
As part of his AAPA efforts he published the anti-Prohibition novel Red Likker. After the repeal of Prohibition, Frankfort Distilleries recruited him to compile a recipe book to remind consumers who were out of practice how to mix a good drink; the cartoon The Woods Are Full of Cuckoos caricatures Cobb as "Irvin S. Frog". Cobb has been described as having a round shape, bushy eyebrows, full lips, a triple chin, with a cigar always hanging from his mouth, he married the former Laura Spencer Baker of Georgia. Their daughter, Elizabeth Cobb, was an author, she published the novel She Was a Lady and the nonfiction My Wayward Parent, a book about her father. Her first husband was Jr. son of the ornithologist Frank Michler Chapman. Cobb's granddaughter was a television actress of the early 1950s, she married journalist Mike Wallace as his second wife. Cobb was honored in 1915 with the march "The War Correspondent" by G. E. Holmes, published by the John Church Company. Cobb was inducted into the Kentucky Writers' Hall of Fame on February 2, 2017.
When Cobb died in New York City in 1944, his body was sent to Paducah for cremation. His ashes were placed under a dogwood tree; the granite boulder marking his remains is inscribed "Irvin Shrewsbury Cobb 1876-1944 Back Home". Cobb wrote a letter detailing his desired funeral arrangemen
Illinois is a state in the Midwestern and Great Lakes region of the United States. It has the fifth largest gross domestic product, the sixth largest population, the 25th largest land area of all U. S. states. Illinois is noted as a microcosm of the entire United States. With Chicago in northeastern Illinois, small industrial cities and immense agricultural productivity in the north and center of the state, natural resources such as coal and petroleum in the south, Illinois has a diverse economic base, is a major transportation hub. Chicagoland, Chicago's metropolitan area, encompasses over 65% of the state's population; the Port of Chicago connects the state to international ports via two main routes: from the Great Lakes, via the Saint Lawrence Seaway, to the Atlantic Ocean and from the Great Lakes to the Mississippi River, via the Illinois Waterway to the Illinois River. The Mississippi River, the Ohio River, the Wabash River form parts of the boundaries of Illinois. For decades, Chicago's O'Hare International Airport has been ranked as one of the world's busiest airports.
Illinois has long had a reputation as a bellwether both in social and cultural terms and, through the 1980s, in politics. The capital of Illinois is Springfield, located in the central part of the state. Although today's Illinois' largest population center is in its northeast, the state's European population grew first in the west as the French settled the vast Mississippi of the Illinois Country of New France. Following the American Revolutionary War, American settlers began arriving from Kentucky in the 1780s via the Ohio River, the population grew from south to north. In 1818, Illinois achieved statehood. Following increased commercial activity in the Great Lakes after the construction of the Erie Canal, Chicago was founded in the 1830s on the banks of the Chicago River at one of the few natural harbors on the southern section of Lake Michigan. John Deere's invention of the self-scouring steel plow turned Illinois's rich prairie into some of the world's most productive and valuable farmland, attracting immigrant farmers from Germany and Sweden.
The Illinois and Michigan Canal made transportation between the Great Lakes and the Mississippi River valley faster and cheaper, new railroads carried immigrants to new homes in the country's west and shipped commodity crops to the nation's east. The state became a transportation hub for the nation. By 1900, the growth of industrial jobs in the northern cities and coal mining in the central and southern areas attracted immigrants from Eastern and Southern Europe. Illinois was an important manufacturing center during both world wars; the Great Migration from the South established a large community of African Americans in the state, including Chicago, who founded the city's famous jazz and blues cultures. Chicago, the center of the Chicago Metropolitan Area, is now recognized as a global alpha-level city. Three U. S. presidents have been elected while living in Illinois: Abraham Lincoln, Ulysses S. Grant, Barack Obama. Additionally, Ronald Reagan, whose political career was based in California, was born and raised in the state.
Today, Illinois honors Lincoln with its official state slogan Land of Lincoln, displayed on its license plates since 1954. The state is the site of the Abraham Lincoln Presidential Library and Museum in Springfield and the future home of the Barack Obama Presidential Center in Chicago. "Illinois" is the modern spelling for the early French Catholic missionaries and explorers' name for the Illinois Native Americans, a name, spelled in many different ways in the early records. American scholars thought the name "Illinois" meant "man" or "men" in the Miami-Illinois language, with the original iliniwek transformed via French into Illinois; this etymology is not supported by the Illinois language, as the word for "man" is ireniwa, plural of "man" is ireniwaki. The name Illiniwek has been said to mean "tribe of superior men", a false etymology; the name "Illinois" derives from the Miami-Illinois verb irenwe·wa - "he speaks the regular way". This was taken into the Ojibwe language in the Ottawa dialect, modified into ilinwe·.
The French borrowed these forms, changing the /we/ ending to spell it as -ois, a transliteration for its pronunciation in French of that time. The current spelling form, began to appear in the early 1670s, when French colonists had settled in the western area; the Illinois's name for themselves, as attested in all three of the French missionary-period dictionaries of Illinois, was Inoka, of unknown meaning and unrelated to the other terms. American Indians of successive cultures lived along the waterways of the Illinois area for thousands of years before the arrival of Europeans; the Koster Site demonstrates 7,000 years of continuous habitation. Cahokia, the largest regional chiefdom and urban center of the Pre-Columbian Mississippian culture, was located near present-day Collinsville, Illinois, they built an urban complex of more than 100 platform and burial mounds, a 50-acre plaza larger than 35 football fields, a woodhenge of sacred cedar, all in a planned design expressing the culture's cosmology.
Monks Mound, the center of the site, is the largest Pre-Columbian structure north of the Valley of Mexico. It is 100 feet high, 951 feet long, 836 feet wide, covers 13.8 acres. It contains about 814,000 cubic yards of earth, it was topped by a structure thought to have measured about 105 feet in length and 48 feet in width, covered an area 5,000 square feet, been as much as 50 feet high, making its peak 150 feet above the level of the pl
U.S. Route 45
U. S. Route 45 is a major north–south United States highway and a border-to-border route, from Lake Superior to the Gulf of Mexico. A sign at the highway's northern terminus notes the total distance as 1,300 miles. US 45 is notable for incorporating, in its maiden alignment, the first paved road in the South, a 49-mile segment in Lee County, Mississippi. Let to contract in July 1914, the concrete highway opened on November 15, 1915; as of 2006, the highway's northern terminus is in Ontonagon, Michigan, at the corner of Ontonagon and River Streets, a few blocks from Lake Superior. M-64 terminated there as well until its rerouting in October 2006 to use the newly built Ontonagon River Bridge, its southern terminus is in Mobile, Alabama, at an intersection with U. S. Route 98. US 45 is concurrent with unsigned SR 17 between Mobile and Vinegar Bend, just north of Deer Park, in Washington County, Alabama. From Vinegar Bend to the Mississippi state line, US 45 is concurrent with unsigned SR 57. U. S. Highway 45 is part of a designated hurricane evacuation route in Mississippi.
It is four-laned from its point of entry from Alabama, at the town of State Line, to the Tennessee line just north of Corinth, along the way serving the towns of Waynesboro, Meridian and Tupelo. At Brooksville, U. S. 45 splits away from U. S. 45 Alternate and serves the towns of Columbus and Aberdeen before rejoining U. S. 45 Alternate south of Tupelo. The alternate roadway provides a more direct and four-laned route between Meridian and Tupelo, bypassing Columbus to the west and, more Starkville to the east. Major junctions of U. S. 45 in Mississippi include U. S. Route 84 at Waynesboro, Interstate 20/59 at Meridian, U. S. Route 82 at Columbus, Interstate 22/U. S. Route 78 at Tupelo and U. S. Route 72 at Corinth; each of these junctions is an interchange and, with the exception of Waynesboro, each is part of a freeway segment. The Mississippi section of U. S. 45 is defined at Mississippi Code Annotated § 65-3-3. From the Mississippi state line U. S. 45 extends north past Selmer and Jackson to Three Way, just north of Jackson.
At Three Way, the highway splits into U. S. 45E and U. S. 45W. From Three Way to the northeast, U. S. 45E extends past Milan Martin and is concurrent with unsigned State Route 43 for most of the route's length past except for short segments at South Fulton and Martin, where it is cosigned with State Route 216 and State Route 215 respectively. From Three Way to the northwest, U. S. 45W extends past Humboldt and is concurrent with unsigned State Route 5 to Union City and with U. S. 51 to the junction with U. S. 45E less than a quarter mile south of the Kentucky state line. Mainline U. S. 45, concurrent with U. S. 51, continues north into Kentucky. U. S. 45 enters Kentucky at Fulton northeast past Mayfield heads directly north into Paducah as a four-lane highway. In Paducah, U. S. 45 serves as a major artery, intersecting with Interstate 24 at exit 7, intersecting US 60 and 62. U. S. 45 leaves Kentucky from Paducah's northern border across the two-lane, metal-grate Brookport Bridge to Brookport, Illinois across the Ohio River.
In the state of Illinois, U. S. 45 runs from a bridge across the Ohio River from Paducah, through Shawnee National Forest and north to the Wisconsin border east of Antioch, Illinois. With a length of 428.99 miles in Illinois, U. S. 45 is the longest numbered route in Illinois. In its progress north from the Ohio River U. S. 45 first joins Interstate 24 as far as Vienna heads northeast through Harrisburg and north through Fairfield, Effingham, Champaign, Urbana and Kankakee straight north through the western suburbs of Chicago in Will County, Cook County and Lake County to the Wisconsin border. U. S. 45 enters the state in southeast Wisconsin. It runs concurrent with Interstate 894 and U. S. Route 41 through the west side of metro Milwaukee to form a major artery through the metropolitan area, it runs north to Fond du Lac. The highway routes near the western shore of Lake Winnebago through Wisconsin. U. S. 45 travels north through Wittenberg and Eagle River, as well as the state and national forests, until it leaves the state at Land O' Lakes and enters Michigan.
US 45 enters Michigan south of Watersmeet. From there, the highway crosses the Western Upper Peninsula through the Ottawa National Forest running north to Ontonagon. US 45 ends just south of Lake Superior in downtown Ontonagon; the terminus was not changed in 2006 despite realignment of M-38 and M-64 from the terminus to a crossing 0.7 miles south. Until March 1935, US 45's northern terminus was in the Illinois area. Prior to the construction of the Interstate Highway system, US 45 was one of the main routes south out of Chicago toward New Orleans, Louisiana. Much of the traffic left US 45 at Effingham, continuing on through Cairo, Illinois along Illinois Route 37.
