Motorists can circle the Washington region via the Capital Beltway.
In the future, the region’s residents may be able to do the same on a version built for cyclists and pedestrians.
As envisioned by planners, the “Bicycle Beltway,” formally known as the National Capital Trail, would be a 60-mile loop circling the region and crossing through Maryland. Virginia and the District. It would make it possible to bike from Silver Spring in the north to Alexandria in the south and points in between. Another more ambitious plan, endorsed by the Transportation Planning Board this month, expands the concept, connecting that loop with other trails in the region to create a more extensive biking network.
