Lumber or timber is a type of wood, processed into beams and planks, a stage in the process of wood production. Lumber is used for structural purposes but has many other uses as well. There are two main types of lumber, it may be surfaced on one or more of its faces. Besides pulpwood, rough lumber is the raw material for furniture-making and other items requiring additional cutting and shaping, it is available in many species hardwoods. Finished lumber is supplied in standard sizes for the construction industry – softwood, from coniferous species, including pine and spruce, hemlock, but some hardwood, for high-grade flooring, it is more made from softwood than hardwoods, 80% of lumber comes from softwood. In the United States milled boards of wood are referred to as lumber. However, in Britain and other Commonwealth nations, the term timber is instead used to describe sawn wood products, like floor boards. In the United States and Canada timber describes standing or felled trees. In Canada, lumber describes cut and surfaced wood.
In the United Kingdom, the word lumber is used in relation to wood and has several other meanings, including unused or unwanted items. Referring to wood, Timber is universally used instead. Remanufactured lumber is the result of secondary or tertiary processing/cutting of milled lumber, it is lumber cut for industrial or wood-packaging use. Lumber is cut by ripsaw or resaw to create dimensions that are not processed by a primary sawmill. Resawing is the splitting of 1-inch through 12-inch hardwood or softwood lumber into two or more thinner pieces of full-length boards. For example, splitting a ten-foot 2×4 into two ten-foot 1×4s is considered resawing. Structural lumber may be produced from recycled plastic and new plastic stock, its introduction has been opposed by the forestry industry. Blending fiberglass in plastic lumber enhances its strength and fire resistance. Plastic fiberglass structural lumber can have a "class 1 flame spread rating of 25 or less, when tested in accordance with ASTM standard E 84," which means it burns slower than all treated wood lumber.
Logs are converted into timber by being hewn, or split. Sawing with a rip saw is the most common method, because sawing allows logs of lower quality, with irregular grain and large knots, to be used and is more economical. There are various types of sawing: Plain sawn – A log sawn through without adjusting the position of the log and the grain runs across the width of the boards. Quarter sawn and rift sawn – These terms have been confused in history but mean lumber sawn so the annual rings are reasonably perpendicular to the sides of the lumber. Boxed heart – The pith remains within the piece with some allowance for exposure. Heart center – the center core of a log. Free of heart center – A side-cut timber without any pith. Free of knots – No knots are present. Dimensional lumber is lumber, cut to standardized width and depth, specified in inches. Carpenters extensively use dimensional lumber in framing wooden buildings. Common sizes include 2×4, 2×6, 4×4; the length of a board is specified separately from the width and depth.
It is thus possible to find 2×4s that are four and twelve feet in length. In Canada and the United States, the standard lengths of lumber are 6, 8, 10, 12, 14, 16, 18, 20, 22 and 24 feet. For wall framing, "stud" or "precut" sizes are available, are used. For an eight-, nine-, or ten-foot ceiling height, studs are available in 92 5⁄8 inches, 104 5⁄8 inches, 116 5⁄8 inches; the term "stud" is used inconsistently to specify length. Under the prescription of the Method of Construction issued by the Southern Song government in the early 12th century, timbers were standardized to eight cross-sectional dimensions. Regardless of the actual dimensions of the timber, the ratio between width and height was maintained at 1:1.5. Units are in Song Dynasty inches. Timber smaller than the 8th class were called "unclassed"; the width of a timber is referred to as one "timber", the dimensions of other structural components were quoted in multiples of "timber". The dimensions of timbers in similar application show a gradual diminution from the Sui Dyansty to the modern era.
The length of a unit of dimensional lumber is limited by the height and girth of the tree it is milled from. In general the maximum length is 24 ft. Engineered wood products, manufactured by binding the strands, fibers, or veneers of wood, together with adhesives, to form composite materials, offer more flexibility and greater structural strength than typical wood building materials. Pre-cut studs save a framer much time, because they are pre-cut by the manufacturer for use in 8-, 9-

A railroad car float or rail barge is an unpowered barge with rail tracks mounted on its deck. It is used to move railroad cars across water obstacles, or to locations they could not otherwise go, is towed by a tugboat or pushed by a towboat; as such, the car float is a specialised form of the lighter, as opposed to a train ferry, self-powered. During the Civil War Herman Haupt used huge barges fitted with tracks to enable military trains to cross the Rappahannock River in support of the Army of the Potomac. Beginning in the 1870s, the Baltimore and Ohio Railroad operated a car float across the Potomac River, just south of Washington, D. C. between Shepherds Landing on the east shore, Alexandria, Virginia on the west. The ferry operation ended in 1906; the B&O operated a car float across the Baltimore Inner Harbor until the mid-1890s. It connected trains from Philadelphia to Washington, D. C. and points to the west. The operation ended after the opening of the Baltimore Belt Line in 1895; the Port of New York and New Jersey had many car float operations, which lost ground to the post-World War II expansion of trucking, but held out until and the rise of containerization in the 1970s.
These car floats operated between the Class 1 railroads termini on the west bank of Hudson River in Hudson County, New Jersey and the numerous online and offline terminals located in Brooklyn, Staten Island, Bronx & Manhattan. Class 1 railroads in the New York Harbor area providing car float services were: Baltimore and Ohio Railroad Central Railroad of New Jersey Delaware and Western Railroad Erie Railroad and Erie Lackawanna Railroad Lehigh Valley Railroad Long Island Rail Road New York Central Railroad New York, New Haven and Hartford Railroad Pennsylvania Railroad Reading Railroadas well as the offline terminal railroads Brooklyn Eastern District Terminal Bush Terminal/Industry City Brooklyn Army Terminal Hoboken Manufacturers Railroad Jay Street Connecting Railroad New York Dock Railway Pouch Terminal East Jersey Railroad and Terminal Co. Car float service was provided to many pier stations and waterfront warehouse facilities by the above-mentioned railroads. At their peak, the railroads had 3,400 employees operating small fleets totalling 323 car floats, plus 1,094 other barges, towed by 150 tugboats between New Jersey and New York City.
Abandoned float bridges are preserved as part of this history at: Gantry Plaza State Park in Long Island City, Queens. A complete list is available at Surviving Float Bridges of New York Harbor Freight cars do not run in the East River Tunnels nor the North River Tunnels, in part due to inadequate tunnel clearances of the New York Tunnel Extension; the Bay Coast Railroad operated a 2-barge car float connecting Virginia's Eastern Shore with the city of Norfolk, Virginia across the Chesapeake Bay. Between 1912–1936, the Erie Railroad operated a car float service on the Chicago River in Chicago, Illinois.

Windsor, Ontario – Detroit, Michigan BC Rail. until 1955 railcars were barged from North Vancouver to Squamish. A large number of isolated BC pulp mills had chemicals and freight moved by car floats; the Alaska Railroad provides the Alaska Rail Marine rail barge service from downtown Seattle, Washington to Whittier on the central Alaskan mainland. Additionally, CN Rail provides the Aqua Train rail barge service from Prince Rupert, British Columbia to Whittier; the only remaining car float service in operation in the Port of New York and New Jersey is operated by New York New Jersey Rail. This company, operated by the bi-state government agency Port Authority of New York & New Jersey is the successor to the New York Cross Harbor Railroad. Car float service operates between 65th Street / Bay Ridge Yard in Brooklyn, New York and Greenville Yard in Jersey City, New Jersey.

British Columbia is the westernmost province of Canada, located between the Pacific Ocean and the Rocky Mountains. With an estimated population of 5.016 million as of 2018, it is Canada's third-most populous province. The first British settlement in the area was Fort Victoria, established in 1843, which gave rise to the City of Victoria, at first the capital of the separate Colony of Vancouver Island. Subsequently, on the mainland, the Colony of British Columbia was founded by Richard Clement Moody and the Royal Engineers, Columbia Detachment, in response to the Fraser Canyon Gold Rush. Moody was Chief Commissioner of Lands and Works for the Colony and the first Lieutenant Governor of British Columbia: he was hand-picked by the Colonial Office in London to transform British Columbia into the British Empire's "bulwark in the farthest west", "to found a second England on the shores of the Pacific". Moody selected the site for and founded the original capital of British Columbia, New Westminster, established the Cariboo Road and Stanley Park, designed the first version of the Coat of arms of British Columbia.
Port Moody is named after him. In 1866, Vancouver Island became part of the colony of British Columbia, Victoria became the united colony's capital. In 1871, British Columbia became the sixth province of Canada, its Latin motto is Splendor sine occasu. The capital of British Columbia remains Victoria, the fifteenth-largest metropolitan region in Canada, named for Queen Victoria, who ruled during the creation of the original colonies; the largest city is Vancouver, the third-largest metropolitan area in Canada, the largest in Western Canada, the second-largest in the Pacific Northwest. In October 2013, British Columbia had an estimated population of 4,606,371; the province is governed by the British Columbia New Democratic Party, led by John Horgan, in a minority government with the confidence and supply of the Green Party of British Columbia. Horgan became premier as a result of a no-confidence motion on June 29, 2017. British Columbia evolved from British possessions that were established in what is now British Columbia by 1871.
First Nations, the original inhabitants of the land, have a history of at least 10,000 years in the area. Today there are few treaties, the question of Aboriginal Title, long ignored, has become a legal and political question of frequent debate as a result of recent court actions. Notably, the Tsilhqot'in Nation has established Aboriginal title to a portion of their territory, as a result of the 2014 Supreme Court of Canada decision in Tsilhqot'in Nation v British Columbia; the province's name was chosen by Queen Victoria, when the Colony of British Columbia, i.e. "the Mainland", became a British colony in 1858. It refers to the Columbia District, the British name for the territory drained by the Columbia River, in southeastern British Columbia, the namesake of the pre-Oregon Treaty Columbia Department of the Hudson's Bay Company. Queen Victoria chose British Columbia to distinguish what was the British sector of the Columbia District from the United States, which became the Oregon Territory on August 8, 1848, as a result of the treaty.
The Columbia in the name British Columbia is derived from the name of the Columbia Rediviva, an American ship which lent its name to the Columbia River and the wider region. British Columbia is bordered to the west by the Pacific Ocean and the American state of Alaska, to the north by Yukon Territory and the Northwest Territories, to the east by the province of Alberta, to the south by the American states of Washington and Montana; the southern border of British Columbia was established by the 1846 Oregon Treaty, although its history is tied with lands as far south as California. British Columbia's land area is 944,735 square kilometres. British Columbia's rugged coastline stretches for more than 27,000 kilometres, includes deep, mountainous fjords and about 6,000 islands, most of which are uninhabited, it is the only province in Canada. British Columbia's capital is Victoria, located at the southeastern tip of Vancouver Island. Only a narrow strip of Vancouver Island, from Campbell River to Victoria, is populated.
Much of the western part of Vancouver Island and the rest of the coast is covered by temperate rainforest. The province's most populous city is Vancouver, at the confluence of the Fraser River and Georgia Strait, in the mainland's southwest corner. By land area, Abbotsford is the largest city. Vanderhoof is near the geographic centre of the province; the Coast Mountains and the Inside Passage's many inlets provide some of British Columbia's renowned and spectacular scenery, which forms the backdrop and context for a growing outdoor adventure and ecotourism industry. 75% of the province is mountainous. The province's mainland away from the coastal regions is somewhat moderated by the Pacific Ocean. Terrain ranges from dry inland forests and semi-arid valleys, to the range and canyon districts of the Central and Southern Interior, to boreal forest and subarctic prairie in the Northern Interior. High mountain regions both north and south subalpine climate; the Okanagan area, extending from Vernon to Osoyoos at the United States border, is one of several wine and cider-produci
Esquimalt Royal Navy Dockyard
Esquimalt Royal Naval Dockyard was a major British Royal Navy yard on Canada's Pacific coast from 1842 to 1905, subsequently operated by the Canadian government to the present day. The naval dockyard was located in Esquimalt, British Columbia, adjacent to Esquimalt Harbour and the city of Victoria, to replace a base in Valparaíso, Chile as the home of the Royal Navy's Pacific Station and was the only Royal Navy base in western North America. A hydrographic survey carried out by HMS Pandora around 1842, determined that the location and depth of the Esquimalt Harbour would make it acceptable for use as a British naval port on the west coast of North America; the following year James Douglas went out to Vancouver Island intending to set up a trading post for the Hudson's Bay Company. After looking at the shores of Esquimalt Harbour he decided they were too densely wooded for development so he opted to build what would become Fort Victoria on the shores of the adjacent Victoria Harbour and thereby establish what would become the city of Victoria.
Pandora Avenue in Victoria is named in honour of the survey ship, which in turn was named after Pandora of Greek mythology. In 1848 HMS Constance became the first Royal Navy vessel based there, she was commanded by Captain George William Courtenay, after whom Courtenay, British Columbia is named. From 3 July 1850 to February 1854 Augustus Leopold Kuper was Captain of HMS Thetis from her commissioning at HMNB Devonport, he sailed her to the southeast coast of America and to Esquimalt. Kuper Island in the Strait of Georgia, off the east coast of Vancouver Island, was named for Captain Kuper after he surveyed the area from 1851–1853. Thetis Island and Thetis Lake are named for the survey ship. In 1852 sailors from the Thetis built a trail through the forest linking the Esquimalt Harbour with the Victoria Harbour and Fort Victoria; the trail would be paved and is now known as Old Esquimalt Road. In the summer of 1854 several ships, including President, Trincomalee and Virago set out from Valparaíso and sailed across the Pacific Ocean stopping at Marquesas Islands on to Honolulu where they met a French fleet of warships.
In late August the combined fleets sailed to Russia to engage in the Siege of Petropavlovsk at which Commander-in-Chief Pacific Station David Price died. Captain of the Pique Frederick William Erskine Nicolson was brevetted and took command of the British naval forces from 31 August 1854 until the arrival of the next Commander-in-Chief. On 25 November 1854 Rear-Admiral Henry William Bruce, at the West Africa Squadron was appointed Commander-in-Chief, Pacific. Upon arrival at Esquimalt Bruce asked Governor James Douglas to provide the navy with a hospital to receive the expected sick and wounded from the Crimean War. In 1855 three wooden huts were built on Duntze Head, which would be known as Hospital Point; the buildings were the first shore establishment of the Royal Navy at Esquimalt. In 1859 the British Colony of Vancouver Island started to construct lighthouses on the approaches to Esquimalt and Victoria Harbours in part to support the Royal Navy and in part to support civilian navigation amidst the Fraser gold rush and other gold rushes.
Fisgard Light was illuminated on 16 November 1860 and Race Rocks Light was lit on 26 December 1860. In 1865 the facilities in Esquimalt were recognized as an alternate base for the Pacific Station, based in Valparaíso; the emphasis of the station started shifting more to British Columbia as the United Kingdom's economic interests shifted northward. The move allowed the Admiralty to avoid involvement in the Chincha Islands War between Spain and Peru. In the late 1860s and early 1870s any navy vessel in need of hull repair at Esquimalt had to be taken to shipyards in Seattle, Washington in the United States. To remove the dependence on American shipyards a graving dock was constructed at Esquimalt starting in 1876; the graving dock was commissioned in 1887. HMS Cormorant became the first vessel to use the new drydock on 20 July 1887. In its first seven years of use the graving dock serviced 70 navy ships. From 1887 through 1927 the graving dock averaged work on 21 vessels per year; the naval graving dock was put out of use until HMCS Coaticook docked there on 31 August 1945.
Now over a century old, the dock is used to service HMC ships and is part of the Fleet Maintenance Facility. Esquimalt was vacated by the British Royal Navy at sunset on 1 March 1905; the Canadian Department of Marine and Fisheries took over control of the shore establishment and the responsibility of enforcing control of Canada's maritime interests in the area after the Royal Navy left. After passage of the Naval Service Act in 1910 there was a Canadian Naval Service that controlled the base and the CNS became the Royal Canadian Navy in 1911. Although the original graving dock was large enough to accommodate the largest ships in the British Pacific fleet at the time of its construction, by the early 20th century larger ships were being built. In 1924, the government of Canada built a larger graving dock 500 meters distant 48.436548°N 123.424716°W / 48.436548. Today, this dock is a separate facility named Esquimalt Graving Dock, it is operated by Public Services and Procurement Canada and is the largest non-military hard bottom dry dock on the west coast of the Americas.
In February 1942, RMS Queen Elizabeth spent two weeks in the Esquimalt Graving Dock refitting and adding 3,000 extra berths for troopship duty. Stabilizer pockets have been built into the concrete walls of the drydock; this new f
A train ferry is a ship designed to carry railway vehicles. One level of the ship is fitted with railway tracks, the vessel has a door at the front and/or rear to give access to the wharves. In the United States, train ferries are sometimes referred to as "car ferries", as distinguished from "auto ferries" used to transport automobiles; the wharf has a ramp, a linkspan or "apron", balanced by weights, that connects the railway proper to the ship, allowing for the water level to rise and fall with the tides. While railway vehicles can be and are shipped on the decks or in the holds of ordinary ships, purpose-built train ferries can be loaded and unloaded by roll-on/roll-off as several vehicles can be loaded or unloaded at once. A train ferry, a barge is called a car float or rail barge. An early train ferry was established as early as 1833 by the Kirkintilloch Railway. To extend the line over the Forth and Clyde Canal in Scotland, the company began operating a wagon ferry to transport the rolling stock over the canal.
In April 1836, the first railroad car ferry in the U. S. Susquehanna, entered service on the Susquehanna River between Havre de Grace and Perryville, Maryland; the first modern train ferry was Leviathan, built in 1849. The Edinburgh and Newhaven Railway was formed in 1842 and the company wished to extend the East Coast Main Line further north to Dundee and Aberdeen; as bridge technology was not yet capable enough to provide adequate support for the crossing over the Firth of Forth, five miles across, a different solution had to be found for the transport of goods, where efficiency was key. The company hired the up-and-coming civil engineer Thomas Bouch who argued for a train ferry with an efficient roll-on roll-off mechanism to maximise the efficiency of the system. Custom-built ferries were to be built, with railway lines and matching harbour facilities at both ends to allow the rolling stock to drive on and off the boat. To compensate for the changing tides, adjustable ramps were positioned at the harbours and the gantry structure height was varied by moving it along the slipway.
The wagons were loaded off with the use of stationary steam engines. Although others had had similar ideas, it was Bouch who first put them into effect, did so with an attention to detail; this led a subsequent President of the Institution of Civil Engineers to settle any dispute over priority of invention with the observation that "there was little merit in a simple conception of this kind, compared with a work carried out in all its details, brought to perfection."The company was persuaded to install this train ferry service for the transportation of goods wagons across the Firth of Forth from Burntisland in Fife to Granton. The ferry itself was built by a partner of the firm Grainger and Miller; the service commenced on 3 February 1850. It was called "The Floating Railway" and intended as a temporary measure until the railway could build a bridge, but this was not opened until 1890, its construction delayed in part by repercussions from the catastrophic failure of Thomas Bouch's Tay Rail Bridge.
The largest train ferry built is MS Skåne on the Trelleborg-Rostock route, built in 1998, 200 meters long, 29 meters wide, with six tracks plus two on an elevator to the lower deck, having a total length of track of 1,110 meters. Train ferries sink because of sea hazards, although they have some weaknesses linked to the nature of transporting trains "on rail" on a ship; these weaknesses include: Trains are loaded at a rather high level, making the ship top-heavy. The train deck is difficult to compartmentalise, so that sloshing flood water can destabilise the ship; the sea doors where the trains go in and out are a weakness if placed at the rear of the ship. The train carriages need to be secured lest they break away and roll around on long, open-water routes; the Ann Arbor Railroad of Michigan developed a system of making cars secure, adopted by many other lines. Screw jacks were placed on the corners of the railcar and the car was raised to take its weight off of its wheels. Chains and turnbuckles were hooked onto the rails and tightened.
Clamps were placed behind the wheels on the rails. Deckhands engaged in continual tightening of the gear during the crossing; this system held the cars in place when the ship encountered rough weather. Some accidents have occurred at the slip during loading. Train ferries list when heavy cars are loaded onto a track on one side while the other side is empty. Normal procedure was to load half of a track on one side, all of the track on the other side, the rest of the original track. If this procedure was not followed, results could be disastrous. In 1909, SS Ann Arbor No. 4 capsized in its slip in Manistique, Michigan when a switching crew put eight cars of iron ore on its portside tracks. The crew got off without loss of life; the Japanese train ferry, Toya Maru, sank during typhoon Marie on 26 September 1954, killing more than a thousand. Four other train ferries, Seikan maru No.11, Kitami Maru, Tokachi Maru and Hidaka Maru sank on that day. At the time, Japanese train ferries did not have a rear sea-gate, because engineers believed that in-rushing water would flow out again and would not pose a danger.
However, when the frequency of waves bears the wrong relationship to the length of a ship, each wave arrives as the water f
Burrard Dry Dock
Burrard Dry Dock Ltd. was a Canadian shipbuilding company headquartered in North Vancouver, British Columbia. Together with the neighbouring North Van Ship Repair yard and the Yarrows Ltd. yard in Esquimalt, which were absorbed, Burrard built over 450 ships, including many warships built and refitted for the Royal Navy and Royal Canadian Navy in the First and Second World Wars. 1894 – Alfred "Andy" Wallace begins building wooden fish boats at False Creek area of Vancouver, British Columbia. These boatworks was abandoned. 1905 – Wallace Shipyards is incorporated. The following year the company establishes a new, larger shipyard at the foot of Lonsdale Avenue in North Vancouver. 1911 – July 11, the shipyard is destroyed by fire but is rebuilt. 1914–18 – During the First World War, Wallace Shipyards is contracted to make shells for 18-pounder guns builds 6 large cargo schooners and 3 freighters – the first deep-sea steel-hulled ships built in Canada – for the merchant marine. To build the wooden schooners, Number 2 Yard is established west of the Squamish Indian Band reserve.
In 1917, Wallace leases Number 2 yard to the William Lyall Shipbuilding Company, which built 27 wooden ships there before it closes in 1920. 1921 – Wallace Shipyards becomes Burrard Dry Dock Company. Four years the company installs the first floating drydock in Vancouver. 1928 – Burrard Dry Dock builds the St. Roch, the first ship to travel the Northwest Passage from the Pacific Ocean to the Atlantic Ocean, the first ship to circumnavigate North America. 1929 – Clarence Wallace becomes president following the death of his father Alfred. 1940–45 – Burrard Dry Dock becomes the busiest Canadian shipyard during the Second World War, building 109 "Park" and "Fort" Liberty-class freighters, along with assorted corvettes, minesweepers and LSTs, several Admiralty maintenance ships, such as the Beachy Head class. The company opens a second shipyard, South Yard, at the foot of McLean Avenue in Vancouver to help meet the wartime demand. Burrard Dry Dock converts and outfits 19 escort carriers for the Royal Navy.
Employment peaks at 14,000 workers, including 1,000 women.) 1946 – Yarrows Ltd. of Esquimalt, BC is acquired from Yarrow Shipbuilders of the United Kingdom. 1951 – The adjacent North Vancouver Ship Repairs shipyard is acquired. 1967 – In a move to consolidate the shipbuilding industry on the Pacific Coast, Burrard Dry Dock acquires the assets of Victoria Machinery Depot in Victoria, British Columbia and closes its shipyard. 1972 – The Wallace family sells the shipyard to Cornat Industries, part of Vancouver-based and held Canadian Forest Products conglomerate. The ship yards were consolidated and renamed Burrard-Yarrows Group Burrard Yarrows Corporation. 1982 – Panamax class drydock, related cranes, machine shop are completed in North Vancouver. 1985 – Burrard-Yarrows Corporation becomes Versatile Pacific Shipyards 1992 – Cancellation of the Polar 8 Project leads to bankruptcy of Versatile Pacific Shipyards. The North Vancouver shipyard is closed and the last employees are laid off; the floating drydocks along with support buildings at the eastern end of the shipyard are acquired by a new company, Vancouver Drydock, still in operation today.
1993 – The Esquimalt shipyard closes. The following year its assets are taken over by Victoria Shipyard, now part of Seaspan Marine Corporation. 1997 – City of North Vancouver study recommends mixed-use development on the site. 2000 – Real estate developer Pinnacle International creates a plan for the site involving multiple condo towers, commercial space and public amenities. Three of the former shipyard buildings, two shipyard cranes and the stern and steam engines from the former HMS Flamborough Head, built here in 1944, are to be preserved as part of the development. 2006 – The City of North Vancouver announces a plan for a new National Maritime Museum of the Pacific with federal and provincial funding to be located on the property. The city negotiates with Pinnacle International for increased density and building heights in return for approving development of the site and to make room for the museum. 2010 – The National Maritime Museum project is shelved after the provincial government failed to commit funding.
The continued vision for site, to be housed inside the former Machine Shop building, is for a resident and tourist destination including a regional attraction and supporting retail uses. The Machine Shop building is temporarily dismantled and removed during site construction, while the former Pipe Shop and Coppersmiths Shop have been restored for retail use; the shipyard cranes have been restored and now tower over the development, one above Shipyard Plaza and one above Craneway Plaza. Signs and dioramas around the site tell the history of the former shipyard.
