Due to the rapid growth in the South County area, the Department of Transportation has partnered with Hillsborough County to develop long-term solutions to help alleviate traffic congestion in the area of the Interstate 75 interchange and Big Bend Road (CR 672). 

Proposed improvements on this design-build project include the complete reconstruction of the I-75 interchange at Big Bend Road.

A new northbound entrance ramp for westbound Big Bend Road traffic and a new southbound exit ramp for westbound Big Bend Road traffic will be built, eliminating the need for westbound Big Bend Road traffic to cross the roadway to access I-75. The storage area at the base of the northbound I-75 exit ramp will be increased. In addition, a left turn lane onto westbound Big Bend Road will be built. 

The southbound I-75 exit lane approaching Big Bend Road will be extended and dual right-turn lanes will be added to westbound Big Bend Road. A triple right-turn lane controlled by a signal from the southbound I-75 exit ramp to eastbound Big Bend Road will be added, and the westbound Big Bend Road to southbound I-75 and eastbound Big Bend Road to northbound to NB I-75 movements will include signalized dual left-turn movements.  

Big Bend Road will be widened between Covington Garden Drive and Simmons Loop from a 4-lane divided road to 6 lanes and will include enhanced pedestrian, bicycle, and bus facilities. The existing bridges on Old Big Bend Road and Big Bend Road will be rebuilt. Construction activities are anticipated to begin in early 2022.
