Old Chesterbrook Road
|Bridge rehabilitation over Pimmit Run in McLean|
Project at a Glance
Old Chesterbrook Road bridge re-opened to traffic on Aug. 31, 2012. See the news release.
About the Project
This project replaced the old and worn timber decking and steel beams with a more durable concrete superstructure.
- Repairs to existing abutments
- New approach sidewalks on the north side of Old Chesterbrook Road, a pedestrian crossing, and connection to Pimmit Run walking trail
- Relocation of sewer pipe and a utility pole
The new bridge continues to carry two lanes of traffic and a sidewalk, although the sidewalk and curb-to-curb width are eacg slightly wider (one to two feet). The road alignment and elevation were slightly changed to match the bridge.
The old bridge was built in 1978 and had been structurally deficient for several years. In January 2012, inspections revealed advanced deterioration of the structural steel that downgraded the bridge’s condition rating and reduced the load-carrying capacity limit to 20 tons. This project was accelerated and approved for emergency procurement to replace the deteriorated elements and restore full-load capacity as soon as possible.
