PROJECT HIGHLIGHTS: I-4/LEE ROY SELMON EXPRESSWAY INTERCHANGE - TAMPA, FLORIDA

The I-4/Lee Roy Selmon Expressway Interchange is a new north-south toll road, which will connect Interstate 4 with the Selmon Expressway in Tampa, Florida. This elevated roadway will link these two major east-west corridors and significantly improve the movement of people and goods.
