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. While they serve as important commuter routes to suburban and urban communities in the Tampa Bay region providing access to jobs, medical facilities, universities and cultural resources, the Downtown Interchange is a known chokepoint.

Tampa Bay Next will provide multimodal transportation choices to:

  • Distribute traffic more evenly for a growing and changing downtown and urban core
  • Efficiently move people and goods with connectivity throughout the region
  • Enhance travel speeds to key destinations and reduce backups
  • Connect neighborhoods with greenway and trail connections

Wait, didn’t you fix that already?

FDOT completed operational improvements to the Downtown interchange in 2006. These improvements were meant to be interim and FDOT has had a long-standing plan to redesign and reconstruct the Downtown Tampa Interchange since the late 1980s. The interchange is part of the original Tampa Interstate Study.

The Downtown Tampa Interchange, Tampa’s Westshore Interchange, and the Westshore to Downtown Tampa Corridor 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). FDOT began theTampa Interstate Study (TIS) Supplemental Environmental Impact Statement (SEIS) in 2017, working with the Federal Highway Administration (FHWA).

FDOT has been engaging with the community to receive input on alternative design concepts for the SEIS and held a public meeting in October 2017 to review the concepts and get community input. FDOT also held a second public workshop in May 2019 to further review proposed alternative options. A public hearing was held in February 2020, and FHWA approved the SEIS in September 2020.
