The Coast Guard is establishing a temporary safety zone on the navigable waters at mile 1.0 Danvers River within a 100-yard radius of the center point of the Kernwood Avenue Bridge between Salem MA and Beverly MA. The temporary safety zone is necessary to protect personnel vessels and the marine environment from potential hazards created during bridge repairs. When enforced entry of vessels or persons into this zone is prohibited unless specifically authorized by the Captain of the Port Boston or a designated representative.
