Just off Lake Boca Raton on the Boca Raton Inlet, the Boca Raton Inlet Bascule Bridge carries state Route A1A traffic north across the inlet. This bridge has a restricted opening schedule and opens each quarter-hour from 7 a.m. to 6 p.m., and on demand at all other times. The bridge has a 23-foot closed vertical clearance with 45 feet of horizontal space at the center span.
Mariners are advised to proceed through the Boca Raton Inlet only if they posses prior local knowledge of the area. Despite dredging, the inlet is quite dynamic and continually shoaling. Depending on the 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.)
