Maryland Route 223 is a state highway in the U.S. state of Maryland. The state highway runs 12.65 miles (20.36 km) from a dead end near Livingston Road in Piscataway north to Mellwood Road in Melwood. MD 223 passes through suburban areas of southern Prince George's County, including the community of Woodyard south of Andrews Air Force Base between MD 5 in Clinton and MD 4 in Melwood. The highway was constructed from Clinton to near Piscataway in the 1920s and early 1930s. MD 223 was extended west to Livingston Road in Piscataway and east to MD 4 in the mid-1950s. MD 223's interchanges with MD 4 and MD 5 were built in the mid-1960s and early 1990s, respectively.

Maryland Route 5 is a 74.34-mile (119.64 km) long state highway that runs north–south in the U.S. state of Maryland. The highway runs from Point Lookout in St. Mary's County north to the Washington, D.C. border in Suitland, Prince George's County. MD 5 begins as two-lane undivided Point Lookout Road which runs from Point Lookout to an intersection with MD 235 in the northern part of St. Mary's County. Point Lookout Road passes through rural areas as well as the county seat of Leonardtown. After the MD 235 intersection, the route becomes four-lane divided Three Notch Road and continues into Charles County, where it becomes Leonardtown Road. Here, the route bypasses Hughesville and continues north toward the Waldorf area, which it bypasses to the east on Mattawoman Beantown Road. The route merges onto U.S. Route 301 and enters Prince George's County, splitting from US 301 at an interchange in Brandywine. From here, MD 5 continues north on Branch Avenue, running through suburban areas, before becoming a freeway as it passes Andrews Air Force Base and has an interchange with Interstate 95 (I-95)/I-495. Past the Capital Beltway, the route runs through suburban areas of Hillcrest Heights and Suitland before reaching the Washington, D.C. border, where Branch Avenue SE continues, crossing Pennsylvania Avenue SE and eventually terminating at Randle Circle.
