US 421 in Virginia
According to transporthint, US 421 is a US Highway in the US state of Virginia. The road forms an east-west route in the extreme southwest of the state, between Bristol on the Tennessee border and the Kentucky border. A significant portion of the route is double-numbered with other roads, US 23 and US 58. The road is 106 kilometers long.

West of Pennington Gap, US 421 in Kentucky enters the state of Virginia from London and continues southeast through mountainous terrain. At Pennington Gap you cross the alternate route of US 58 and a little further past Woodway the road merges with the actual US 58. Both roads then start double-numbering to the east, as a 2×2 divided highway. At Duffield, US 23 from Pikeville in Kentucky also merges into it, creating a triple numbering. The road traverses several steep ridges of the Appalachian Mountains. At Weber City, the US strikes 23direction Kingsport and Johnson City in Tennessee and US 58 and US 421 continue together towards Bristol. The road then has one lane in each direction and leads through hilly and wooded area, parallel to the border with Tennessee. At Bristol you first cross the Interstate 81. Then you cross US 11, which is double numbered with US 19. US 421 then turns into Tennessee. US 58 continues east. US 421 in Tennessee then runs to Winston-Salem in North Carolina.
US 421 was added to the network of US Highways in 1930, but at the time only ran in the state of North Carolina. The route was terminated in Virginia in 1932 to replace the older US 411 between Cumberland Gap and Bristol. So this was an east-west route in far southwest Virginia. However, this situation only existed for 1 year, in 1933 the route was shortened to Bristol and the section from Cumberland Gap to Bristol became part of the US 58. In 1935, however, it was decided to extend US 421 again to Cumberland Gap, this time with a double numbering with US 58. This was reversed around 1945-1946, so that US 421 again ended in Bristol. The current route was established in 1950 when US 421 was extended from Bristol into Kentucky.
The upgrade history of US 421 coincides with that of US 58, only the double numbering with US 58 has been widened to a 2×2 divided highway between south of Pennington Gap and Gate City. The Gate City bypass opened in October 1966, and a new 2×2 lane of US 58 opened west of Gate City in January 1970. In February 1970, a new route through the mountains opened between Duffield and Clinchport, cutting a detour around the ridge. This is directly constructed with 2×2 lanes. In March 1994 a new track opened over the mountainsides at Stickleyville with 2×2 lanes.
US 48 in Virginia
US 48 is a US Highway in the US state of Virginia. The road forms an east-west route from the West Virginia border to Interstate 81 at Strasburg. US 48 is 21 kilometers long.
US 48 runs through the far east of the Appalachian Mountains, from the West Virginia border to Interstate 81 in Strasburg. The US 48 is single lane.
In 1965, the Appalachian Development Highway System was created, which was to improve connections in the isolated and underdeveloped Appalachian Mountains. One of these connections was Corridor H, which forms US 48. It connects central West Virginia to the Washington region via I-66.
The route in Virginia is also known as State Route 55. The route is to be expanded to a 2×2 divided highway up to I-81 near Strasburg, but that has not yet been completed.
US 50 in Virginia
According to travelationary, US 50 is a US Highway in the US state of Virginia. The road forms an east-west route in the north of the state, from the Winchester region to the Washington, DC metropolitan area. The road is 80 miles long.

US 50 in West Virginia comes from Clarksburg and crosses the Virginia border in mountainous terrain. Within a few kilometers the US 50 becomes a 2×2 divided highway and descends to the town of Winchester. US 50 runs through downtown but Winchester also has a bypass. In Winchester, US 11 and US 522 are crossed and there is a connection to Interstate 81.
After Winchester, US 50 coincides with US 17 for a while. This section is also a 2×2 divided highway and leads over the low Ashby Gap, a mountain pass in the Blue Ridge Mountains. Shortly thereafter at Paris, US 17 and US 50 split. US 50 then becomes a single carriageway into the western suburbs of Washington, DC. US 50 quickly becomes a busier road, changing from 1×2 to 2×3 lanes within a few miles and passes south of Dulles Airport. In the suburb of Chantilly follows a cloverleaf cloverleaf with State Route 28.
US 50 then forms an important urban arterial, with several important intersections designed as interchanges, including Interstate 66 and State Route 286. In Fairfax one crosses US 29, after which US 50 has a major interchange with Interstate 495knows. Around this interchange, the US 50 has been developed as a highway with 2×3 lanes and grade separated intersections. The US 50 then forms an important urban arterial with 2×2 lanes and has grade-separated elements. In Arlington, US 50 runs around the west and north sides of Arlington National Cemetery. In Arlington, many offices are located near US 50. US 50 then crosses the Theodore Roosevelt Bridge over the Potomac River with I-66 to Washington, DC. US 50 in Washington, DC then continues straight through downtown.
US 50 is one of the original US Highways of 1926. Originally the route passed through the center of Fairfax, but about 1928 a double numbering with US 29 was created along Fairfax, which was led over a new bypass in 1935. Between the 1940s and the 1960s, a number of minor route diversions were already carried out west of the Washington region.
As early as 1941, the first section of US 50 was widened to 2×2 lanes, between Fairfax and Washington, DC. The Fairfax bypass was widened to 2×2 lanes in the period 1942-1947. During the 1960s and early 1970s, US 50 was systematically widened to 2×2 lanes west and east of Winchester.
Originally, US 50 crossed the Potomac River via the Arlington Memorial Bridge, a 1932 stone arch bridge. In 1964, the Theodore Roosevelt Bridge opened over the Potomac River, part of I-66. The US 50 was also routed over this.
In the suburbs of Washington, DC, US 50 has several grade separated intersections and connections. This was largely realized in or before the 1980s. Also characteristic is the complex interchange with I-495, which was reconstructed in 2011-2012 for the construction of the express lanes on I-495.
