This $55 million Design-Build project provides traffic congestion relief by the removal of the two at grade and signalized lights that caused traffic delays along the Route 234 intersection in Manassas, Virginia.
The new interchange minimizes traffic signals, and improves the roadway and overall safety by separating pedestrian and vehicular traffic with a new pedestrian bridge over Route 234. The project included the creation of an extensive network of shared-use paths enhancing mobility for bicyclists and pedestrians along the interchange and ties traffic into Brentsville and Dumfries roads and Prince William County Parkway.
Two new bridges divert traffic from the north and south across the Parkway, allowing vehicles traveling along Brentsville Road to avoid stopping.
Wagman Heavy Civil is the general contractor for the Design-Build project designed by Rinker Design Associates. For more information on the project, visit the Prince William County project website.
Key Challenges & Project Details
- The construction work took place near the Bradley Family Cemetery, which dates back to the 1860s. About 40 people are buried there, primarily members of the Hornbaker family who own property near Route 234 and Prince William Parkway.
- The limits of disturbance were marked and monitored to ensure the area was not disturbed.
- The interchange acts as a gateway for area residents driving to I-95, Route 1, and I-66.
- Significant project features that improved the intersection included roadway improvement, stormwater and drainage improvements, minimization of traffic signals, utility relocation, and right-of-way acquisition.
- Wagman’s Geotechnical Construction Group self-performed the pile installation for the bridge abutments on the two new bridges built over Route 234.
