I-275 / I-4 Downtown Tampa Interchange (DTI)
The I-275 / I-4 Downtown Interchange (I-275 DTI) in Tampa, Florida, was originally designed in the 1960s to accommodate traffic volumes of approximately 60,000 vehicles per day. Today, nearly 200,000 vehicles travel through the interchange daily, making a major upgrade essential to ensure safer mobility.
Commissioned by the Florida Department of Transportation, the project is part of the Tampa Bay NEXT program and will provide multimodal transportation options designed to optimize the movement of people and goods, increase travel speeds, and better connect local communities.
The contract includes, among other works, the redesign and reconstruction of the highway interchange, encompassing the design and construction of improvements aimed at enhancing traffic flow and road safety. These works include ramp widening, traffic management optimization, the upgrade of all roadway signage, and the installation of noise barriers.
In the first half of 2026 completion of bridges 1, 8 and 9, enabled opening of the road to traffic and commencement of the project’s next phases.
The I-275 / I-4 Downtown Interchange is also set to become one of the primary hurricane evacuation routes serving the Tampa Bay area.
