The William H. Dalton Memorial Bridge carries US Route 6/ State Route 28 (the Cranberry Highway) over Cohasset Narrows at the Bourne – Wareham Town Line.

The Middlesex Corporation replaced the existing structure with a 350’-long 3-span bridge. The superstructure consists of an 8” high performance concrete deck supported by 10 New England Bulb Tee (NEBT) pre-cast and pre-stressed concrete girders. The substructure is comprised of granite clad wall piers and integral abutments.

The four travel lanes were upgraded from 10’ to 12’ and two 4-foot shoulders were added. A new 6’ sidewalk was provided on the south side to match the upgraded sidewalk on the north side which ties into the existing sidewalk on the Bourne side of the project.
