The Downtown Tampa Interchange project will improve safety and operations of the I-275/I-4 interchange in Tampa.

Improvements include: 

• widening the existing single lane ramp from southbound I-275 to eastbound I-4 to two lanes
• widening the existing single lane ramp from westbound I-4 to northbound I-275 to two lanes
• widening the existing two-lane ramp from westbound I-4 to southbound I-275 to three lanes
• changing the eastbound exit ramps from I-4 into Ybor City/East Tampa by providing access at 14th/15th streets instead of 21st/ 22nd streets
• widening the existing eastbound frontage road (13th Avenue) to two lanes
• adding an additional merge lane on northbound I-275 between I-4 and the Martin Luther King Jr. exit
• 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
