Public outreach ►

This project is located on Route 720 (Smithland Road) in Rockingham County. The bridge over Interstate 81 will be replaced with a new structure. The current bridge was built in 1960 and is nearing the end of its service life.

The proposed bridge will be constructed approximately 30 feet to the west of the existing bridge and will be 5.5-feet higher. The project includes realigning the bridge approaches.

The new bridge will have two through lanes and one turn lane. A five-foot wide sidewalk will be located on the west side of the project.

Additionally, the intersections of Route 720 (Smithland Road) and Route 718 (Old Furnace Road) will be improved to make Route 720 the through street.  Dedicated turn lanes will also be constructed on Route 720. 

In 2011 Route 720 had an average daily traffic count of 4,100 vehicles per day.  By the design year of 2039 the estimated average daily traffic volume is 6,610 vehicles per day.

The total estimated cost for this project is $10,220,470, including $926,359 for preliminary engineering, $582,256 for right of way and $8,711,855 for construction.

Benefits 

This project enhances safety on Route 720 by replacing a deteriorating bridge structure with a new bridge that is able to support modern traffic both in volume and vehicle weights. The height of the new bridge increases vehicle clearance for I-81 traffic.  Changes at the Route 720 intersection with Route 718 will improve traffic flow and provide better sight distance for drivers.
