Transform 66 Outside the Beltway

The project transforms Interstate 66 between I-495 and Gainesville into a multimodal corridor with express lanes, shared-use path, interchange improvements, and new park-and-ride lots.

Transform 66 Inside the Beltway

The project added a lane to I-66 East between the Dulles Toll Road and Fairfax Drive, improved access to the West Falls Church Metrorail Station, and constructed a bridge over Route 29 for the W&OD Trail.
