Contractors working for the U.S. Army Corps of Engineers move stone that is being delivered to the Sea Gate work site in Brooklyn January 21, 2015. The work at Sea Gate is an improvement upon the larger Coney Island Coastal Storm Risk Management Project and involves the construction of four stone T-groins, a stone spur on the West 37th Street Groin and reinforcement of the Norton Point Dike and the West 37th Street Groin. The project also includes the placement of roughly 125,000 cubic yards of sand, which will take place later in construction.
