The Downtown Tampa Interchange project will improve the safety and operations of the I-275/I-4 interchange in Tampa. Improvements include: 
Southbound I-275 to Eastbound I-4

  • Providing a two-lane exit and constructing a new exit ramp bridge (to the inside of the interchange) from southbound I-275 to eastbound I-4
  • Changing the eastbound exit ramp from I-4 into Ybor City/East Tampa by relocating access at 14th/15th Streets instead of 21st/ 22nd Streets
  • Widening the existing eastbound I-4 frontage road (13th Avenue) to two lanes

Westbound I-4 to Northbound I-275

  • Widening the existing single lane ramp from westbound I-4 to northbound I-275 to two lanes
  • Adding an additional merge lane on northbound I-275 between I-4 and the Martin Luther King Jr. exit

Westbound I-4 to Southbound I-275

  • Widening the existing two-lane ramp from westbound I-4 to southbound I-275 to three lanes
  • Widening the shoulders on southbound I-275 between Palm Avenue and Jefferson Street
  • Shifting the exit ramp from southbound I-275 into downtown Tampa to the west of the current alignment

To construct the project, heavy machinery will be used during daytime and nighttime hours and at times, may produce noise, vibration, and lighting impacts.

Work requiring lane closures will occur at night between 9 p.m. and 6:30 a.m. Occasionally, interstate ramps may close at night between 11 p.m. and 5 a.m.

This project is expected to finish in 2027.
