Hammonasset Beach is located in Hammonasset State Park in Madison. The beach extends along the entire southwestern shore of Hammonasset Point.

Work on the project, completed in June 1955, consisted of:

• Widening a 10,000-foot stretch of beach by the direct placement of sand. The beach was widened by 50 feet at the east end, increasing to 100 feet approaching the west end.
• Constructing two training walls at Toms Creek on the western end of the beach. One wall is 320 feet long, and the other is 400 feet long.
• Constructing an 800-foot-long groin at Hammonasset Point on the eastern end of the beach.

The project cost $489,600.
