WASHINGTON — You can bike the Mt. Vernon Trail without owning a bike soon.

Arlington County has struck a deal with the National Park Service to install Capital Bikeshare docking stations in the parking lot on Theodore Roosevelt Island and at Gravelly Point, just north of Reagan National Airport.

No timeline for installation of the stations has been set.

The only other Capital Bikeshare docking station on National Park Service land is at the Iwo Jima Memorial in Rosslyn.

The 18 mile Mt. Vernon Trail runs from Rosslyn to George Washington’s home at Mount Vernon.

“Both Gravelly Point and Theodore Roosevelt Island are favorite spots for Arlingtonians and visitors as they enjoy the Mt. Vernon Trail,” said Arlington County Board Chair Katie Cristol. “Installing bikeshare stations at these spots also makes these National Park Service resources more accessible, bringing nature and history closer to our residents.”

The agreement with the Park Service means the county is responsible for installing and maintaining the Capital Bikeshare docking stations.

The Park Service has no financial liability.
