The West Flagler Street Bascule Bridge is the sixth bridge that the boater encounters when traveling west along the Miami River from Brickell Point. The bridge has a 35-foot closed vertical clearance with 75 feet of horizontal clearance in the center span. The bridge operates on a restricted opening schedule. There are no openings Monday through Friday from 7:30 to 9 a.m., and then again from 4:40 to 6 p.m.. The bridge opens on demand at all other times.
Depending on schedule, the bridge can be opened by horn signal (one long, one short) or by hailing the bridge tender on VHF Channel 09. (All bridges in the state of Florida must be hailed on VHF Channel 09.)
