Sound Beach Avenue Bridge Project Will Begin April 11

GREENWICH, CT — The Greenwich Department of Public Works announced on Tuesday that major construction on the Sound Beach Avenue Bridge will begin April 11.

A temporary vehicular detour utilizing Harding Road and Forest Avenue will be in effect from April 11 to July 1. Pedestrians will be routed through Binney Park during construction.

Accelerated Bridge Construction techniques will be used in this project, which can significantly reduce road closure time.

The existing Sound Beach Avenue Bridge was built in 1925 and rehabilitated in 1977 while adding an additional culvert to the south to relieve flooding. But over the years, the bridge has fallen into disrepair.

The current structure consists of two spans, a concrete deck span, and a concrete box culvert span, which creates a center pier. The bridge will be replaced by a single-span precast concrete structure. Eliminating the center pier will increase the hydraulic efficiency, DPW said, noting that 14,500 vehicles use the bridge every day.

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.

The new bridge will match the look of the Wesskum Wood Road Bridge and pedestrian bridges within Binney Park, DPW said. Masonry fascia comprised of rounded stones, deep grout and capstones will be installed in the new structure.
