Located at Intracoastal Waterway Mile Marker 1013.7, the Parker Bascule Bridge has a 25-foot closed vertical clearance and 94 feet of horizontal clearance at the center span. The bridge operates on a restricted schedule and opens only on the quarter and three-quarter hour.
This area is often filled with vessels traveling at a high rate of speed, and a close watch is necessary.
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.)
