Sound Beach Avenue Bridge (No. 03954)
The Sound Beach Avenue bridge was completed the first week of May 2023.
Located on Sound Beach Avenue, adjacent to Binney Park, this critical project replaced the deteriorating bridge built in 1925 and utilized by approximately 14,500 vehicles daily. The project cost $2.5 million dollars and was funded through the Local Transportation Capital Improvement Program (LOTCIP) grant from the Connecticut Department of Transportation (CTDOT). Construction plans were prepared by Weston & Sampson, of Rocky Hill, CT and the contractor for this project is A. Vitti Excavators, LLC of Stamford, CT. Town of Greenwich
To increase hydraulic efficiency in an area prone to coastal flooding, the new bridge design eliminated the center pier and is a single-span precast concrete structure. Town of Greenwich Department of Public Works (DPW) incorporated feedback from the Town’s Planning and Zoning Commission and community when designing this project. The new bridge is faced with natural rounded stones to complement Binney Park and the New England aesthetic of the area.
Bridge Project Features
- Built brand new bridge – corrected existing structural and hydraulic deficiencies of the bridge.
- Improved water flow – increased hydraulic efficiency in an area prone to coastal flooding. The project also installed new drainage structures to improve run-off.
- Minimized construction impacts – employed Accelerated Bridge Construction (ABC) techniques to significantly reduce road closure time.
- Pedestrian safety and accessibility – relocated the sidewalk on the east side to the interior of the bridge and eliminated the old wood pedestrian bridge.
- Aesthetics – matched the look and feel of the scenic area by adorning the new bridge with natural rounded stones. The gas utility was removed from view. New landscaping has been added to all four corners of the bridge.
Minimizing Construction Impacts
This project employed Accelerated Bridge Construction (ABC) techniques to significantly reduce road closure time. The roadway was closed for only three months and a detour was implemented to initiate the construction. The project took approximately a year to complete. DPW regularly coordinated with utility companies that have utilities located on or near the bridge. Construction crews had to continuously handle water flowing under the bridge into Binney Pond.
