1 month ago Share Longboat Key town projects manager Charlie Mopps credited the contractor's equipment, which allows for less expensive sand dredging. Boating and beach activities are closed east of the Longboat Pass Bridge on the north end of Longboat Key as work proceeds on an emergency dredging project on Canal 1A. The town awarded the Canal 1A bid to Duncan Seawall Dock and Boat Lift, LLC for $81,755, according to Longboat Key town projects manager Charlie Mopps. Work began Jan. 25. “[Duncan] had some equipment problems last week. Like they had a track that broke, so they’re bringing in a track, fixing it on the beach,” Mopps said. “They got it fixed.”
