About the Project

This project will replace the Towlston Road bridge (Route 676) over Rocky Run in Great Falls.

Plans were underway to replace the original 1949 bridge when it was washed out by Tropical Storm Lee in September 2011. Under an emergency contract, crews built five steel pipe culverts as a temporary structure to re-open the road to traffic as soon as possible. The current bridge structure is sound but does not have adequate hydraulic capacity to handle high water during storms.

Under a research project sponsored by the Virginia Center for Transportation Innovation and Research and the Federal Highway Administration, this project will replace the bridge using new Geosynthetic Reinforced-Integrated Bridge System technology for Abutments. The project also includes:

  • An additional 2 feet of shoulder on either side
  • Aesthetic treatments on railings and abutments (see rendering)
  • Stream restoration to stabilize Rocky Run and guide creek through the restored opening
  • Overhead and underground utility coordination

Estimated project cost
Preliminary engineering: $433,000
Construction: $910,000
Total: $1.34 million

No right-of-way is required for this project.

Tentative project schedule
February 2014 - Advertise for construction
Early Summer 2014 - Road closed and major construction begins
End Summer 2014 - Construction completed

Traffic Impacts

The bridge will be tentatively closed to traffic during the summer 2014 so that crews can finish the replacement before the fall. Signs will direct drivers to detour via Old Dominion Drive and Georgetown Pike (see proposed detour map).
