About
This project is a comprehensive effort to modernize Tampa's Westshore Interchange through roadway and infrastructure improvements. The ultimate design for the I-275/SR 60 interchange includes a comprehensive reconfiguration to enhance traffic flow, capacity, and safety. The redesigned interchange will feature new flyover ramps with direct connections to I-275 north, SR 60, and Tampa International Airport, along with dedicated lanes for local and airport traffic to reduce weaving conflicts. Wider lanes and longer merge areas will provide safer entry and exit movements, while enhanced drainage, lighting, and landscaping will improve both safety and the overall appearance of the corridor. Together, these improvements will transform the interchange into a safer, more efficient connection for commuters, residents, and visitors.
The project is being delivered as a phased design-build, with Priority 1A serving as the initial construction phase, which is currently underway.
Priority 1A – Currently Under Construction
The Priority 1A phase focuses on reconstructing key interchange elements to improve traffic operations, safety, and local connectivity. Improvements include:
- Reconstructing portions of I-275 and SR 60 with updated general-use lanes
- Constructing the northbound I-275 Express Lanes from the Howard Frankland Bridge to the future Reo Street Bridge
- Replacing the existing loop ramp from eastbound SR 60 to northbound I-275 with a new flyover ramp
- Constructing a new flyover ramp from the Howard Frankland Bridge to SR 60 and the Tampa International Airport
- Adding a new southbound I-275 entrance ramp from Reo Street
- Reconnecting local roadways at Reo Street, Occident Street, and Trask Street to improve local access and circulation
- Enhancing pedestrian and bicycle connectivity through shared-use paths and aesthetic improvements.
The future phases are scheduled for funding in 2030 and 2032.
