Route 29 over Little Rocky Run
|Bridge replacement in Fairfax County|
Project at a Glance
About the Project
This project will replace the structurally deficient Lee Highway (Route 29) bridge over Little Rocky Run and widen it to three lanes in each direction. It includes a ten-foot trail on the south side of the bridge, and a five-foot sidewalk to the north.
The current bridge was built in 1932, and is in overall poor condition. The current sufficiency rating for the existing bridge is 20.9 on a scale of 0 (poor) to 100 (very good). The sufficiency ratings developed by the Federal Highway Administration serve as a prioritization tool to allocate funds. The rating considers adequacy, whether the bridge is functionally obsolete, and the service level provided to the public.
The Route 29 bridge carries approximately 36,000 vehicles per day.
During construction, drivers can expect some off-peak lane closures and traffic shifts from 9:30 a.m. to 3:30 p.m. and 10 p.m. to 5 a.m. Monday to Thursday; 9:30 a.m. to 2 p.m. Friday; and overnight on weekends as crews replace the bridge. All work is weather permitting.
By mid April 2014, there will be a slight traffic shift towards the median on Northbound Route 29 to make room for construction of the new Northbound bridge.
Clearing and grubbing work is complete. Erosion and control measures have been installed.
The 24” watermain relocation for Fairfax County is in progress on the south side of the project along Northbound Route 29. This watermain work is being done to make room for the new bridge over the Little Rocky Run in order to widen the existing Route 29 from four to six lanes. The 24’’ watermain is slated for completion in early April.
