This is a long way from DC, but the Virginia Department of Conservation and Recreation recently completed the draft master plan of the Beaches to Bluegrass Trail, a bike trail all the way across southern Virginia from Virginia Beach to Cumberland Gap (It looks like it stops short of Kentucky, but comes close. It connects to Tennessee at Bristol and North Carolina near the Dan River.) From the draft plan
One of the earliest references to the Beaches to Bluegrass Trail is in the 1979 Virginia Outdoors Plan, where it is referred to as the Southside Virginia Trail. The Southside Virginia Trail was referred to as the Trans Virginia Southern Trail in subsequent updates of the Virginia Outdoors Plan. The Beaches to Bluegrass name was conceived in 2008 when tourism officials involved with the trail heard of a book, Beach to Bluegrass: Places to Brake on Virginia’s Longest Road, by Joe Tennis, and thought that name better captured the concept of a statewide trail. With the author’s permission, the Beaches to Bluegrass Trail is the official title in the 2013 update of the Virginia Outdoors Plan.
