About
This design-build project is building a new southbound/westbound interstate bridge over Old Tampa Bay (from Tampa to St. Petersburg) between Hillsborough and Pinellas counties in Florida.
The new bridge will consist of eight lanes: four general-use lanes and four express lanes (two lanes from St. Petersburg to Tampa and two lanes from Tampa to St. Petersburg). In addition, a bicycle/pedestrian pathway separated from the roadway is under construction.
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 into final alignment, the existing northbound/eastbound (St. Petersburg to Tampa) bridge will be removed.
Estimated project completion is early 2026.
As of December 5, 2024:

Closures
-
I-275 (Howard Frankland Bridge) between Hillsborough and Pinellas counties
Lane closures: Sunday, February 9 through Saturday, February 15 nights from 9 p.m. to 6 a.m. -
Northbound I-275 Travel Lanes on the Howard Frankland Bridge Closing Monday and Tuesday Nights
Tampa Bay, FL - Motorists traveling northbound on I-275 toward the Howard Frankland Bridge will have to detour off the interstate using Gandy Boulevard (Exit 28) nightly on Monday, February 10 and Tuesday, February 11, from 11 p.m. to 5 a.m., weather permitting.
Electronic message boards and temporary signage will assist northbound I-275 motorists traveling around the closure via the posted detour route of Roosevelt Boulevard, Gandy Boulevard, and Dale Mabry Highway.
Other roadways (Roosevelt Boulevard, Bayside Bridge, Courtney Campbell Causeway, and Memorial Highway) will remain accessible and may provide an alternate route.
Motorists should add approximately 30 minutes of travel time as traffic congestion and delays may occur while traveling on these roadways.
These overnight closures are necessary for crews to install overhead sign structures as part of the new southbound I-275 (Howard Frankland Bridge) bridge project between Hillsborough and Pinellas counties.
