Work set to start on $252m Virginia road scheme

A design-build team of Dewberry and Shirley Contracting is starting work this month on a US$252.8m scheme to improve the Route 7 corridor in Virginia.

The project will widen Route 7 from a four-lane divided highway to a six-lane divided highway from Reston Avenue to Jarrett Valley Drive. Other upgrades will include a new pedestrian tunnel beneath Route 7 at Colvin Run Mill, turn-lane improvements, multiple noise barriers, and a bridge replacement. Pedestrian facilities will be incorporated for the entire length of the project along both sides of Route 7.

Dewberry will carry out all of the design elements of the project including the geometry, structures, hydraulic and stormwater management and traffic control, as well as provide environmental permitting, surveying, and construction quality control (QC) inspection services.

The design-build team will also be responsible for coordinating the Route 7 improvements project with the US$200m Washington Gas transmission line upgrade being performed by the Washington Gas Company.

The project is due for completion in August 2024.
