The Franconia to Lorton Third Track will increase rail capacity and alleviate congestion for passenger and freight services by adding a third mainline track along one of the most heavily traveled sections of rail between DC and Richmond. This additional 6 miles of mainline third track from Franconia to Lorton will creating a continuous third track corridor between Alexandria and Lorton. In addition, the project will construct railroad bridges over Newington Road and Lorton Road, and other infrastructure to accommodate the additional third track. The Franconia to Lorton Third Track Project will be carefully coordinated with the Franconia-Springfield Bypass Project.
