Bayside Bridge, Girder bridge in Pinellas County, Florida

The Bayside Bridge, officially the Dillinger McCabe Bayside Bridge, is a six-lane twin-span girder bridge crossing the northwesternmost end of Tampa Bay between Clearwater and Largo. It carries McMullen Booth Road to 49th Street North, with a SPUI interchange at State Road 60 and a diamond interchange at its south end. The posted speed limit is 55 mph.

The bridge opened in 1993 as a result of a funding initiative based on increased gasoline taxes. This project connected two growing communities and modernized the regional transportation network.

The bridge is named after Bob Dillinger, a longtime Pinellas County public defender, and Bernie McCabe, a long-serving state attorney; the county commission approved the renaming in January 2026, effective February 24, 2026. Drivers also know it as the route linking McMullen Booth Road to 49th Street North, a bypass for congested US 19.

When crossing, be aware that this is a major traffic corridor that can be quite busy during peak hours. Consider traveling during weekends or early morning hours when traffic flows more easily.

The roadway has slight undulations, particularly in the northbound direction, that developed during construction. These surface variations are noticeable to drivers but do not affect safety.
