Route 7 over Dulles Toll Road
|Bridge deck replacement and widening in Fairfax County|
Project at a Glance
About the Project
This project will rehabilitate the Route 7 bridges over the Dulles Toll Road and widen the road from four lanes to six lanes, from approximately Tyco Road to Jarrett Valley Drive.
The superstructure and the two abutments of the existing bridges will be replaced, the substructure will be repaired, and existing piers will be widened to accommodate the additional width for the bridges. The decks of the two existing bridges over the Dulles Toll Road (DTR) will be replaced and widened in the middle to accommodate one extra lane on each bridge. The height of the bridges will be raised to meet the standard clearance requirement of 16.5 feet.
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 widening work will require some additional right-of-way and temporary construction easements.
The bridge will be open for traffic at all times.
