Thanks to Emily Harper for the comment:
This is an update from Nelson County, the owners of the Blue Ridge Tunnel. The Tunnel is closed to the public at this time and any unauthorized persons entering at this time are trespassing. The Tunnel walls are not stable at this time. It is disappointing that some trespassers have been leaving trash and defacing the walls with graffiti.
It is the County’s objective to restore the Tunnel and convert it to a pedestrian trail. Woolpert Inc, our architectural & engineering firm is in the process of determining the most feasible, cost effective methods for rehabilitation and design of the Tunnel and related trails. Once that is complete construction will begin as funds are made available.
We appreciate your interest in the Tunnel, are working to make it safe for your enjoyment, and ask that you stay away until it’s completed.
