This project will widen I-275 and add two tolled express lanes in each direction from north of 38th Avenue N to south of Gandy Boulevard in Pinellas County. One additional tolled express lane, for a total of two in each direction of I-275 will be added from south of Gandy Boulevard to north of 4th Street N.
The project also includes interchange modifications 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.
Shared Use Path along SR 688 (Ulmerton Road): A 12-foot-wide shared use path will be constructed along the north side of SR 688 (Ulmerton Road) from Fountain Parkway N to west of I-275. The shared use path was formerly a separate project (444243-1-52-01) during design, but this work has been combined with the highway project and will be built under the same construction contract.
The roadway and shared use path improvements will tie into the completed Gateway Expressway and active Howard Frankland Bridge projects.
