Virginia: The Old Dominion

Virginia’s Shenandoah Rail Trail will connect towns from Broadway to Front Royal with almost 50 miles of trail alongside the North Fork of the Shenandoah River and the Massanutten Mountain range.

I just found out about this! Similar to the W&OD trail in Northern VA.

Also looks like it's being threatened unfortunately:

We had a BIG surprise this week (not in a good way) that threatens the future of the Shenandoah Rail Trail. A new proposal was presented at the Commonwealth Transportation Board (CTB) meeting on December 9, leaving all of us shocked and frustrated. More recently, VDOT’s Rail-With-Trail assessment looked at restoring rail service alongside a trail. Their cost estimates indicate that attempting to rebuild the railroad and add a trail alongside it would cost roughly four times more than building a standalone trail.
