Scenic Byway: Frederick SR 600 to I-81 (since 6/12/97);
Comments: Corridor H is entirely a West Virginia endeavor at this point. Virginia has shown no interest in making US 48 an expressway-type route. It has posted the route for continuity with West Virginia and that's about it. As of early 2022, Corridor H has been constructed as nearly entirely new alignment from Wardensville WV west to Davis, with more under construction from Kerens to Parsons. West Virginia had been posting US 48 on each new segment as it opened on the road heading westward, but when the route was built to Davis they added US 48 shields along WV 32, US 219, and US 33 for the entirety of the Corridor H designation.
Construction of the segment from Wardensville to the Virginia line is expected within the next few years and that is when to watch for Virginia doing anything on its portion.
US 48 did not appear on a state official map until the 2016 issue, but it had been in several Rand McN issues and was explicitly shown in traffic logs since 2003.
