Drivers through the downtown Tampa interstate interchange, known by locals as “Malfunction Junction,” will face detours this weekend while workers erect steel girders for a new exit ramp.
The Florida Department of Transportation is advising drivers to expect delays and congestion from 12:01 a.m. Saturday to 5 a.m. Monday.
Electronic message boards and temporary signage will assist motorists.
Here are the planned detours:
Driving north on I-275 from Dale Mabry: Follow I-4 (Exit 45B), leave at Exit 3, turn right on Columbus Drive, left on U.S. 41, left on Hillsborough Avenue, then continue west to reenter northbound I-275. (Saturday, 5 a.m.–10 p.m.)
Driving south on I-275 through downtown: Only one lane will be open from Dr. Martin Luther King Jr. Boulevard south into downtown. Continue to Exit 45A and use the temporary ramp to reenter I-275 South.
Driving south on I-275 needing downtown: Exit at 46A, turn right on Floribraska Avenue, left on Tampa Street, then south to reach downtown.
Driving on I-275 South to I-4 East: : This ramp will remain open all weekend.
Driving west on I-4 needing I-275 South or downtown: Take the I-275 North entrance ramp, exit at 46B, go left onto State Road 574 (MLK), and left onto Tampa Street to access I-275 South or other downtown streets. (Saturday 5 a.m.–10 p.m.)
The work is part of a project to improve safety and relieve congestion for drivers exiting or entering the highways. Construction is expected to be completed in 2027.
