Massachusetts drawbridge map — the Cut, the swing, and the lift

Gloucester's Blynman “Cut” bridge opens ~9,500 times a year. New Bedford–Fairhaven swings on the hour each morning and at quarter-past all afternoon. Chelsea Street's lift stops Route 1A traffic for tankers. Every Massachusetts movable bridge, with its opening rule — tap any bridge.

How it works: opening rules come from the US Coast Guard’s Drawbridge Operation Regulations (33 CFR Part 117). MassDOT posts Chelsea Street lift alerts to roadside signs and @LoganToChelsea; New Bedford–Fairhaven runs a published clock (on the hour 6–10 a.m., quarter-past 11:15 a.m.–6:15 p.m.). No structured live feed exists in Massachusetts yet. Also see Seattle and the other state pages on the Maps hub.
