I-275 provides a convenient route for commuters, residents and tourists, but with an abundance of key destinations, congestion leads to traffic delays.

I-275 is a conduit of regional mobility.

The USF area and the surrounding innovation district is a growing healthcare and economic center. This north-south interstate corridor is critical to the efficient movement of people and goods throughout the Tampa Bay area and the state.

Improvements to I-275 N. of Downtown Tampa provide:

• Vital connectivity to regional interstates including I-75 and I-4
• Integration with multimodal choices under development across our region
• Enhanced travel times to healthcare and hospitals, education, tourist destinations, entertainment venues and employment centers
• Access to the University of South Florida and major destination points

The Florida Department of Transportation completed improvements along the I-275 Corridor from the I-4/I-275 Interchange to north of Hillsborough Avenue to improve safety and traffic operations. The project, which completed construction in Spring 2025, added general use capacity, constructed sound barriers, and integrated opportunities for transit.

The improvements included providing dedicated auxiliary lanes from the I-4 ramps to north of Dr. Martin Luther King, Jr. Boulevard and adding one general purpose lane in each direction from north of Dr. Martin Luther King, Jr. Boulevard to north of Hillsborough Avenue. New sound barriers were constructed along the corridor and the improvements provide opportunities for future transit along this corridor with wide shoulders to provide flexibility for future transit bus operations. All of the improvements were be completed within existing right-of-way.

This project began October 2021 and was completed in March 2025.
