I-75 closures for upgrading begin Monday

Expect more nighttime and weekend road closures beginning Monday in Hillsborough County as the Florida Department of Transportation begins repairs and replacement of lanes and ramps along Interstate 75, north and south of Interstate 4.

The project will last nearly two years.

FDOT will replace the concrete travel lanes and ramps of I-75 from south of I-4 to Fowler Avenue, including replacement of the I-75/I-4 concrete interchange ramps with asphalt pavement. There also will be upgrades to I-75 bridges.

The slab replacement work will be done between 8 p.m. and 6 a.m. to minimize impacts to traffic. However, reconstruction of the ramps at the I-4 interchange will require extended weekend closures. Alternate routes will be posted. The ramp closures are not expected to start until after the Strawberry Festival, which ends March 4.

Eventually, bridge deck work will require the three through lanes on I-75 at the I-75/I-4 interchange, a distance of about one mile, to be reduced to two lanes around the clock using barrier walls. To minimize traffic impacts, the bridge deck replacement will be performed in one direction at a time.

The 5-mile project will cost $12.75-million.
