About the Project
This project would repair the structurally deficient Sleepy Hollow Road (Route 613) bridge over Tripps Run in Fairfax County.
The single-span bridge, about 95 feet long, has a reinforced concrete deck supported by eight steel plate girders. The concrete stub abutments are supported on steel piles. The bridge is currently posted for 19 tons (single) and 24 tons (semi).
The superstructure has a condition rating of 3 (very poor). There is major deterioration in some of the beams/diaphragms and bearings near the abutments.
In this project, the girders will be repaired, deteriorated diaphragms/connection plates will be replaced, and bearings will be replaced by the jacking and blocking method. All steel girders and the superstructure will be painted, and the deck will be overlaid with rapid-set concrete. Existing joints will be eliminated to minimize future maintenance costs by introducing deck extensions at both ends of the bridge. Expansion joints will also be replaced.
The deck overlay will be done by stage construction, while two lanes (one lane each direction) will remain open to traffic.
The bridge's substructure has a condition rating of 7 and is generally in good condition. There will be minor repairs to the back walls and abutment seats/breast walls.
Except for repair of the pavement near the bridge, no other work to the bridge approach roadway will be required.
This project is tentatively scheduled for advertisement in summer 2011.
