Recently Completed: Aden Road over Norfolk Southern Railroad in Prince William County

Cost and schedule ►

This project rehabilitated the Aden Road (Route 646) historic truss bridge over the Norfolk Southern Railroad and included a new bridge over the railroad and intersection improvements (including a new median) at Marsteller Drive.

Built in 1882 for the Keystone Bridge Company, the truss bridge was purchased in the early 1900s and moved to Aden Road by Norfolk Southern, who transferred ownership to VDOT in 2014. In March 2014, the weight limit on the one-lane truss bridge was reduced from six tons to four. The bridge was closed in May 2015 due to deterioration revealed in inspections, and was removed from the railroad crossing in January 2016. The new one-lane bridge opened to traffic in December 2016.

VDOT planned to repair the truss bridge and reopen it for northbound use, however, upon removal, the bridge showed substantial structural deficiencies. A revised plan/design was developed with the Virginia Department of Historic Resources and the community that allows the truss bridge to remain on the National Register of Historic Places.

Construction resumed in July 2018 to implement the revised plan/design; the new Aden Road bridge was temporarily closed to facilitate the truss bridge reinstallation and rehabilitation. The truss bridge was put back in place over the railroad in November 2018 and reopened to traffic along with the new bridge in March 2019. The overall project was completed in June 2019.  

Aden Road averages about 3,500 vehicles a day at the railroad crossing.

Estimated Costs
Preliminary Engineering - $1.2 million
Right of Way Acquisition and Utility Relocation - $339,000
Construction - $6.7 million
Total - $8.3 million

This project was financed with federal, state and Prince William County funding. Norfolk Southern donated a construction easement to allow the work to be completed.


The project rehabilited the existing bridge as well as built a new bridge to improve safety, and add capacity to provide two-way traffic for the crossing. The original truss bridge was incorporated into the design to maintain the area's historic character for the community.
