Leaders from Montgomery and Fairfax counties sent a letter to their respective states Tuesday, asking that they work together to provide room for express buses and carpools over the American Legion Bridge.

Fairfax County Board of Supervisors Chairwoman Sharon Bulvoa and Montgomery County Council President Roger Berliner called the Beltway between Virginia’s Dulles Access Road and the Interstate 270 west spur “one of the most congested highways in the Washington Metropolitan Area” and asked Virginia and Maryland to work together to make the best use of Virginia’s new Beltway Express lanes by allowing buses to travel on the shoulder over the American Legion Bridge and into Maryland, or by allowing carpoolers onto the shoulder during rush hours.
