The Washington and Old Dominion right of way is 100 feet by 45 miles. The trains stopped in 1968. Virginia Power strung towers and transmission lines while the NVRPA built the greenway. The length is paved for cyclists and a parallel utility road of crushed rock and sand serves as a bridle access. I used the dirt path for my exercise as it offers more cush, and to avoid mixing it up with the fast 2 wheeled traffic. Starting from mile marker 21 I followed this route to the Sully Rd. overpass just short of marker 24 before doubling back.
