Located just south of the George Bush Boulevard Bascule Bridge at Intracoastal Waterway (ICW) Mile Marker 1039.6, the Atlantic Avenue Bascule Bridge has a restricted opening schedule and is the fourth of five opening bridges within a six-statute mile-long stretch. The bridge has a restricted opening schedule and opens on the hour and 3/4-hour. The bridge has a 12-foot closed vertical clearance with 90 feet of horizontal space at the center span.
Transiting the bridge is easy, but there are two marinas south of the bridge that warrant a lookout for entering traffic. 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.)
