Westshore and Downtown Tampa are two business districts in constant motion. With diverse neighborhoods and businesses located along this corridor, movement between them must improve to support economic vitality.
Congestion on this corridor is a result of constant movement between and through the Westshore area and downtown Tampa business districts.
Improvements to this corridor will:
- Provide travelers with better mobility choices
- Reduce traffic congestion
- Enhance opportunity for reliable travel times
- Improve regional connectivity
- Enhance quality of life for residents and visitors to the region
The planned improvements will preserve a 44-foot median to support future transit operations along I-275 from east of Lois Avenue to east of Rome Avenue.
Tampa’s Westshore Interchange, the Westshore to Downtown Tampa Corridor, and the Downtown Tampa Interchange 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 the Tampa Interstate Study (TIS) Supplemental Environmental Impact Statement (SEIS) in 2017, working with the Federal Highway Administration (FHWA).
FDOT engaged 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.
