Comment: VA 48 is prohibited for all commercial traffic.
VA 48 is only referenced about 3 times in the CTB minutes as part of the Blue Ridge Pkwy, all in reference to land conveyances after the fact.
VA 48 does not show on any printed map I have ever seen from Virginia, but it DOES show on the on-line interactive map at www.virginiadot.org
The Skyline Drive portion of VA 48 has no at-grade intersections with any through road south of US 340 - only interchanges at US 250 and US 33. The Blue Ridge Pkwy has interchanges at all its primary route intersections except US 221 Adney Gap and the two VA 43 intersections. However, there are numerous secondary route at-grade intersections. A lot of these are unpaved, making the "No commercial vehicles" postings at those locations seem a little comical.
VA 48 crosses but does not intersect four primary routes in Virginia: I-77, US 58 Bypass, VA 116, and I-64. Only the VA 116 crossing has no easy, nearby way to make a connection.
The speed limit on the Skyline Drive is mostly 35 and on the Blue Ridge Pkwy is mostly 45. Other than peak fall color season, these routes work okay as through routes, though services on VA 48 itself are quite limited.
The Skyline Drive portion requires a fee as part of entry into Shenandoah National Park. This in effect makes VA 48 through there the longest toll road in Virginia.

VA 48 closer to continuity 1933 Official

The 1933 draft route log had VA 48 west rerouted at Blackstone to replace VA 10 to end at US 221 (really) Burkeville. VA 48 from Blackstone to Keysville would've become part of VA 10.
