HILLSBOROUGH COUNTY, Fla. – Drivers across Hillsborough County should brace for significant delays as a wave of construction projects hits major corridors starting Sunday, March 29, through April 4, 2026.
The Florida Department of Transportation (FDOT) District 7 has scheduled an extensive list of lane closures that will impact everything from the Howard Frankland Bridge to local stretches of US 301.
Commuters crossing into Pinellas County will face the most consistent disruptions. The Howard Frankland Bridge on I-275 will see nightly lane closures from 9 p.m. to 6 a.m. starting Sunday.
Nearby, the Gandy Bridge (US 92) will also experience eastbound lane restrictions, though these are scheduled for the midday hours of 9 a.m. to 3 p.m. beginning Monday.
On the mainland, I-75 travelers near MLK Jr. Boulevard and Fowler Avenue should expect night work from Monday through Friday. However, the most significant long-term impacts involve 24-hour restrictions.
US 301 from Bloomingdale Avenue to MLK Jr. Boulevard is currently under 24-hour lane closures through April 17, while SR 39 (southbound) from Kilgore Road to East Sparkman Road remains restricted around the clock until May 1.

Even more permanent changes are in effect on Frontage Road. The stretch between Cypress Street and Lemon Street is under a continuous road closure 24 hours a day, a condition expected to last until January 2027. Another section of Frontage Road near Cypress Center Drive will remain restricted through late 2026.
Surface street commuters on Dale Mabry Highway, Adamo Drive, and SR 60 should also plan for nightly lane shifts. Most of these projects, including work on SR 674 and Thonotosassa Road under I-4, are timed to occur between 8 p.m. and 6 a.m. to minimize peak-hour congestion, though daytime work will persist at US 301 and Ayersworth Glen Boulevard.
While no official statements were included in the summary, the scale of these closures indicates a heavy push for infrastructure maintenance and upgrades across the county this week. Motorists are advised to check their GPS apps before heading out and to allow extra travel time, especially during late-night and early-morning hours.
