The Town of Greenwich Department of Public Works is announcing that major construction on the Sound Beach Avenue Bridge will commence on April 11, 2022. A temporary vehicular detour utilizing Harding Road and Forest Avenue will be in effect from April 11, 2022, to July 1, 2022. Pedestrians will be routed through Binney Park during construction.
With approximately 14,500 vehicles using the Sound Beach Avenue Bridge every day, this is a critical project that will replace a deteriorating bridge built in 1925. The existing bridge will be replaced by a single-span precast concrete structure. Eliminating the center pier will increase the hydraulic efficiency of the bridge. Accelerated Bridge Construction (ABC) techniques will be utilized in this project, which can significantly reduce road closure time. To complement the scenic area, the Sound Beach Avenue Bridge will match the look of the Wesskum Wood Road Bridge and pedestrian bridges within Binney Park, by installing a masonry fascia comprised of rounded stones, deep grout, and capstones. The three primary purposes of this bridge are to support traffic traveling on Sound Beach Avenue, allow water to flow from Cider Mill Brook into Binney Pond, and allow pedestrians to safely travel to and from their destination.
