Description

The Custis Trail is a hilly, 4mi paved bicycle trail in Arlington County, Virginia that extends from Key Bridge at Rosslyn westward to the Washington & Old Dominion Railroad Trail. It connects at its east end to the Mount Vernon Trail, which continues east and south along the Potomac River to Mount Vernon and at its west end to the Washington & Old Dominion Railroad Trail, which continues northwest to Purcellville, Virginia.The Custis Trail was built alongside Interstate 66 (named the Custis Memorial Parkway in Virginia east of the Capital Beltway). The trail opened in the early 1980s at the same time that the highway did. The trail connects to the Key Bridge into Georgetown near the southern end of the Capital Crescent Trail, and to the Mount Vernon Trail, which provides access to three Potomac River crossings into downtown Washington, D.C. (the Theodore Roosevelt Bridge, the Arlington Memorial Bridge and the George Mason Memorial Bridge (see: 14th Street Bridge)).
