About the Project

This project will widen Route 7 from four lanes to six lanes, approximately from 0.1 mile west of Tyco Road to approximately 0.6 mile west of Tyco Road. The six lane facility will tie into the existing four lanes. The decks of the two existing bridges over Dulles Airport Toll Road (DATR) will be replaced and widened in the middle to accommodate one extra lane on each side of the bridges. A 14 foot wide shared-use path will be built for pedestrians and bikes to travel in each direction. The shared-use path will tie into future trails. The proposed grade of the bridges over DATR will be raised to meet the standard clearance requirement of 16' 6". The superstructure and the two abutments of the existing bridges will be replaced, and the substructure will be repaired. Existing piers will be widened to accommodate the additional width for the bridge. The widening work will require some additional right of way and temporary construction easements.
