I-275 from 38th Ave. N to 4th St. N (FPIDs 449109-1, 444234-1)
Construction Cost: $340 million
Construction Began: August 2025
I-275 from 54th Ave. S to 38th Ave. ( FPIDs 449109-2, 424501-7)
Not currently funded for construction
I-275 is a vital link in the local and regional transportation network and serves as a critical evacuation route in Pinellas County. As a major north-south corridor, I-275 links the Tampa Bay region with the remainder of Florida and the nation, supporting commerce, trade, and tourism.
Currently, there are no continuous travel lanes on I-275 in the southbound direction and only one continuous travel lane in the northbound direction. This is caused by a series of existing left-hand entrance and exit ramps. The corridor does include two travel lanes with one auxiliary lane in each direction from south of 54th Avenue S to I-375. From I-375 to north of 4th Street N, there are three travel lanes with one auxiliary lane in each direction.
Improvements are needed to help improve existing traffic congestion, enhance safety, and better accommodate future travel demands associated with projected population and employment growth.
Current Improvements
To sign-up to receive future construction updates and traffic alerts, please visit: FDOTTampaBay.com.
The current improvements include widening the interstate to add two tolled express lanes in each direction from north of 38th Avenue N to south of Gandy Boulevard, and one additional tolled express lane, for a total of two in each direction, from south of Gandy Boulevard to north of 4th Street N. Interchange modifications will be made at 38th Avenue N, 54th Avenue N, Gandy Boulevard, and Roosevelt Boulevard.
Noise barriers will be constructed from north of 38th Avenue N to Gandy Boulevard and a 12-foot-wide shared use path will be constructed along the north side of Ulmerton Road from Fountain Parkway N to I-275. This path will connect to the shared use path that is currently under construction as part of the Howard Frankland Bridge project.
Future Improvements
Future improvements along the corridor south of 38th Avenue N include the addition of two buffer separated express lanes in each direction from north of I-375 to 38th Avenue N and lane continuity from south of 54th Street South to 38th Avenue N to provide continuous travel lanes for commuters.
