This design-build project is building a new southbound/westbound (from Tampa to St. Petersburg) interstate bridge over Old Tampa Bay between Hillsborough and Pinellas counties in West Central Florida.

The new bridge is being built north of the current southbound/westbound (St. Petersburg to Tampa) interstate bridge.  

The new bridge will consist of eight lanes; four general use lanes, (Tampa to St. Petersburg) and four Express lanes; two lanes from the St. Petersburg side toward Tampa, two lanes from the Tampa side toward St. Petersburg. A bicycle/pedestrian pathway separated from the roadway will is also included. 

The existing southbound/westbound (Tampa to St. Petersburg) bridge will be converted to the new northbound/eastbound I-275 (St. Petersburg to Tampa) .  

Once the new bridge is built and all traffic is moved to the final alignment, the existing northbound/eastbound (St. Petersburg to Tampa) bridge will be removed. 

Construction activities began in the fall of 2020.
