About the Project

Crews rebuilt the bridge over Rocky Run in Great Falls while Fairfax County schools were on summer break. Crews closed the road to through traffic on June 25, 2014 and opened the new bridge on August 29, 2014.

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 temporary crossing was sound but did not have the hydraulic capacity to handle high water during storms.

Under a research project sponsored by the Virginia Center for Transportation Innovation and Research, the research division of VDOT, this project replaced the bridge using new Geosynthetic Reinforced-Integrated Bridge System technology for Abutments. It also incorporated an innovative, prestressed concrete "inverted-T" beam superstructure using lightweight concrete materials. Project features:

  • 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 the creek through the restored opening
  • Overhead and underground utility coordination

No right-of-way was required.
