'Sandy Hook' Squeaks Under Raised Marine Parkway Span
The center span of the Marine Parkway-Gil Hodges Memorial Bridge was raised last Sunday afternoon to allow the Sandy Hook, a dredge returning to Ambrose Channel after dropping off sand at Floyd Bennett field, to pass though. Sources said the dredge moves about 3,500 cubic yards of sand per trip and will be ferrying about 30,000 cubic yards in total. The sand will be used for marsh restoration projects in Jamaica Bay. The bridge has an average vertical clearance of 55 feet when down and 152 feet when fully raised, according to nautical charts. The vast majority of boats do not need the bridge lifted to pass through, but the bridge's ability to lift allows the safe passage of massive, unusual vessels such as the barge that carried a retired Concorde jet from JFK International Airport to the Intrepid Sea-Air-Space Museum in 2003.
