About the Project
This project rehabilitated the Route 7 bridges over the Dulles Toll Road (DTR) and widened the road from four lanes to six lanes between Tyco Road and Jarrett Valley Drive.
Some project highlights:
- Replaced superstructure and two abutments of the existing bridges repaired substructure and widened piers to accommodate additional width for the bridges
- Replaced existing bridge decks and widened with an additional lane on each bridge
- Raised the height of the bridges to meet clearance requirements of 16.5 feet
A new 14-foot-wide shared-use path was built for pedestrians and bikes to travel in each direction that will tie into future trails.
The project was financed with federal, state and Northern Virginia Transportation Authority funding.
