Downtown Tampa Interchange

Tampa is experiencing rapid growth, and the downtown interchange is a known chokepoint.

Tampa’s downtown and surrounding urban core  is rich with cultural and historical resources. The downtown interchange and corridors of I-275, I-4 and the Selmon Expressway are key links in Florida’s interstate freeway system providing freight and passenger mobility. They serve as important commuter routes to suburban and urban communities in the Tampa Bay metropolitan area providing access to jobs, medical facilities, universities and cultural resources.

Wait, didn’t you fix that already?

FDOT completed operational improvements to the Downtown interchange in 2006, but FDOT has had a long-standing plan to redesign and reconstruct the Downtown Tampa interchange. The 2006 improvements can be compared to interim improvements in a home renovation. Homeowners may only have funding to replace their floors and windows, but they know that eventually they should replace the HVAC, plumbing, electrical, etc. as funding becomes available. FDOT has planned on redesigning and rebuilding the Downtown Tampa interchange since the late 1980s. The interchange is part of the original Tampa Interstate Study. The current interchange concept has been designed to modern standards, using the most recent traffic data and demographic projections. The design concept is being evaluated under current environmental assessment policies and procedures and a Locally Preferred Alternative has been identified as part of the SEIS.

PUBLIC HEARING: 

Early 2020

PREFERRED ALTERNATIVE: 

Evaluating Express Lanes and
other concepts

The Downtown Tampa Interchange, Westshore Area Interchange, and the Westshore to Downtown Tampa projects are all part of a long-standing plan to improve and modernize Tampa’s interstate system, originally called the Tampa Interstate Study (TIS). The TIS required the most rigorous evaluation process in transportation planning – an Environmental Impact Statement (EIS).

In response to community feedback, FDOT is working with the Federal Highway Administration to prepare a Supplemental Environmental Impact Statement (SEIS) to determine the preferred alternative for improving Tampa’s interstates and evaluating potential impacts. Express lanes are one of the concepts being evaluated in the SEIS.

During October 2017, FDOT held a public workshop to review the concepts and get community input on which concepts will be carried forward for detailed study. A second public workshop was held in May 2019 to review proposed alternative options.

On October 1, 2019, the Florida Department of Transportation presented information on the Locally Preferred Alternative (LPA) for the Tampa Interstate Study (TIS) Supplemental Environmental Impact Statement (SEIS) to the Hillsborough MPO Board. FDOT will recommend the LPA to the Federal Highway Administration (FHWA) for approval. A public hearing is anticipated to take place in early 2020 and the public is invited to continue to provide comments on the study.
