About the Project

This project is rehabilitating the Route 7 bridges over the Dulles Toll Road (DTR) and widening 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 are being replaced, the substructure is being repaired and existing piers are being widened to accommodate the additional width for the bridges.

The decks of the two existing bridges over the DTR are being replaced and widened in the middle to accommodate one extra lane on each bridge.

The height of the bridges is being raised to meet the standard clearance requirement of 16.5 feet.

A 14-foot-wide shared-use path is being built for pedestrians and bikes to travel in each direction.

The shared-use path will tie into future trails.

The widening work requires some additional right of way and temporary construction easements.

The project is being financed with federal, state and Northern Virginia Transportation Authority funding.

Construction Update

June 2017 - Eastbound and westbound traffic have fully shifted onto the rehabilitated and widened bridges.
