The Capital Crescent Trail (CCT) is a shared use off-road trail from Georgetown, D.C. to Silver Spring, MD suitable for walkers, joggers, bikers, and rollerbladers. The Coalition for the Capital Crescent Trail, an all-volunteer organization, has spearheaded efforts since 1986 to develop this first-class shared use trail. The Trail is a rail-trail, built upon the abandoned railbed of the 11 mile Georgetown Branch of the B&O Railroad. The Trail is now complete as a hard surface trail from Georgetown to Bethesda, and is a packed crushed stone trail suitable for most bikes from Bethesda to Lyttonsville, in west Silver Spring. Four bridges and two tunnels offer trail users gentle gradients and grade-separated roadway crossings.
