Located on the Gulf side of the GIWW near Mile 122, the Johns Pass Bascule Bridge shuffles traffic to and from Treasure Island and Madeira Beach outside of Saint Petersburg. Johns pass is one of the more reliable passes on the Florida Gulf Coast.

Bridge Schedule:

The bridge opens on demand 24 hours a day, seven days a week.

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.)

Local Notices to Mariners:

Local Notices to Mariners are available online from the U.S. Coast Guard.

Navigating the Bridge:

Use NOAA Chart 11411.

The bridge has a closed vertical clearance of 27 feet and 60 feet of horizontal clearance in the center span. Johns Pass is one of the more reliable inlets in the area, with 14-foot controlling depths for most of its length. That as a given, the currents still run strong here and a careful grip on the helm is recommended.
