Hi, I am a Bridge Tender at Main Street bridge. The restricted hours are Monday – Friday 7-8:30am and 4:30-6pm(except Fed holidays). There are no restrictions on Saturday. Also, buoy #82 is now a lighted combination buoy (flashing 4 seconds red). Smooth sailing to all !

Every opening clearance is about 82ft. at Mean High Water (MHW) contrary to NOAA chart 11491 and Coast Pilot. Range of Tide is only about 18 inches. We can give up to 138ft. of clearance if needed with a special slow Highlift procedure.
