About
This design-build project is building a barrier separating northbound I-75 travel lanes from traffic entering and exiting the interstate between the SR 574 (Dr. Martin Luther King Jr. Boulevard) and I-4 exits ramps in Hillsborough County.
A two-lane northbound collector-distributor (CD) roadway is being built east of the current northbound travel lanes within the existing right of way. Traffic entering and exiting northbound I-75 at SR 574 (Dr. Martin Luther King Jr. Boulevard) and I-4 will use the new CD roadway.
In addition, the SR 574 (Dr. Martin Luther King Blvd) interchange will be converted to a diverging diamond interchange.
These changes will improve the efficiency and safety of the interstate in this area.
Construction activities are expected to finish during summer of 2025.
