The Route 340/522 South Fork Bridge project replaced the bridge over the South Fork of the Shenandoah River and the Norfolk Southern Railroad. Additionally, the project reconfigured the intersection of Route 340/522 and Route 55. Along with the bridge, the project reconstructed approximately one mile of roadway on the northern outskirts of the town of Front Royal.

The purpose of the project was to replace the deteriorating South Fork Bridge and to address the severe traffic congestion in the bridge corridor. The new 1,910-foot bridge will has six lanes, features bike and pedestrian facilities, and enhances corridor safety. Improved signs, markings and longer turn-lanes are included. A new left-turn lane was built at 18th Street in Front Royal.

High traffic projections at the Route 340/522 intersection with Route 55 required that non-traditional intersection treatments be considered. The new intersection features an innovative design called a Quadrant Roadway Intersection (QRI).

The total estimated cost for this project was $72.2 million, with $4.9 million for preliminary engineering, $6.3 million for right of way activities, and $61 million for construction.

This project’s design complies with Virginia’s Stormwater Management Act, erosion and sediment control regulations and the Virginia Department of Transportation's approved stormwater management program.

During construction, every reasonable effort was made to protect the environment with respect to dust and erosion control. Access to all properties was maintained. Potential impacts to the flood plains was evaluated and addressed.


The project replaced the existing deteriorating bridge, which did not effectively serve modern traffic and vehicle weights.

 The new, wider bridge helps ease traffic congestion in the corridor and has bicycle and pedestrian facilities.

These features improve multi-modal user safety.

The longer turning lanes and the new left-turn lane at 18th Street increase overall safety in the area.

Improvements at the Route 55 intersection enhance safety and reduce energy consumption by significantly enhancing traffic flow and reducing backups.
