About

All construction activities associated with this project were completed on Saturday, March 8, 2025.

Due to the rapid growth in the South County area, the Florida Department of Transportation partnered with Hillsborough County to develop long-term solutions to help alleviate traffic congestion by reconstructing the I-75 interchange at CR 672 (Big Bend Road) Exit 246.

Improvements on this design-build project:

added a new northbound I-75 entrance ramp from westbound Big Bend Road
added a new southbound I-75 exit ramp to westbound Big Bend Road
increased the storage area at the base of the northbound I-75 exit ramp by adding a left-turn lane onto westbound Big Bend Road
extended the southbound I-75 exit ramp lane approaching Big Bend Road and adding dual right-turn lanes to westbound Big Bend Road
added triple right-turn lane controlled by a signal from the southbound I-75 exit ramp to eastbound Big Bend Road
added signalized dual left-turn movements from westbound Big Bend Road to southbound I-75 and eastbound Big Bend Road to northbound I-75
widened Big Bend Road between Covington Garden Drive and Simmons Loop from a 4-lane divided road to 6 lanes featuring enhanced pedestrian, bicycle, and bus facilities
rebuilt the Old Big Bend Road and Big Bend Road bridges
