U.S. Route 58

U.S. Route 58 is an east–west U.S. Highway that runs for 508 miles (818 km) from U.S. Route 25E just northwest of Harrogate, Tennessee, to U.S. Route 60 in Virginia Beach, Virginia. Until 1996, when the Cumberland Gap Tunnel opened, US 58 ran only inside the commonwealth of Virginia. It was then extended southwest along a short piece of former US 25E, which no longer enters Virginia, to end at the new alignment in Tennessee.

State Route 383 is overlaid on U.S. Route 58 in Tennessee.

U.S. Route 58 is the longest numbered route in Virginia.

Route description

Tennessee

US 58 begins at a trumpet interchange with US 25E, just south of the Cumberland Gap Tunnel. The route travels northeast through the outskirts of Cumberland Gap before crossing into Virginia.

US 58 in Tennessee carries the designation State Route 383.

Virginia

US 58 enters Virginia and travels east to Jonesville, where Alternate US 58 branches off and travels to the north. East of Jonesville, US 58 intersects US 421, and the two routes stay concurrent through Duffield (where the concurrency also picks up U.S. 23), Gate City, Weber City (where the US 23 concurrency ends), and Bristol, where US 58 begins a concurrency with Interstate 81. The two routes stay concurrent until I-81 exit 19 in Abingdon, where US 58 resumes its eastward journey close to the Virginia–North Carolina state line. The route is signed as the J.E.B. Stuart Highway and the A. L. Philpott Memorial Highway. Much of the highway through the region features hairpin turns, steep grades, and load-zoned bridges.

List of former Maryland state highways (400–499)

The Maryland highway system has several hundred former state highways. These highways were constructed, maintained, or funded by the Maryland State Roads Commission or Maryland State Highway Administration and assigned a unique or temporally unique number. Some time after the highway was assigned, the highway was transferred to county or municipal maintenance and the number designation was removed from the particular stretch of road. In some cases, a highway was renumbered in whole or in part. This list contains all or most of the state-numbered highways between 400 and 499 that have existed since highways were first numbered in 1927 but are no longer part of the state highway system or are state highways of a different number. Most former state highways have not had their numbers reused. However, many state highway numbers were used for a former highway and are presently in use currently. Some numbers have been used three times. The former highways below whose numbers are used presently, those that were taken over in whole or in part by another highway, or have enough information to warrant a separate article contain links to those separate highway articles. Highway numbers that have two or more former uses are differentiated below by year ranges. This list does not include former Interstate or U.S. Highways, which are linked from their respective lists.
