Due to the rapid growth in the South County area, the Florida Department of Transportation has 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 include: 

• adding a new northbound I-75 entrance ramp from westbound Big Bend Road
• adding a new southbound I-75 exit ramp to westbound Big Bend Road
• increasing the storage area at the base of the northbound I-75 exit ramp by adding a left-turn lane onto westbound Big Bend Road 
• extending the southbound I-75 exit ramp lane approaching Big Bend Road and adding dual right-turn lanes to westbound Big Bend Road
• adding a triple right-turn lane controlled by a signal from the southbound I-75 exit ramp to eastbound Big Bend Road
• adding signalized dual left-turn movements from westbound Big Bend Road to southbound I-75 and eastbound Big Bend Road to northbound I-75
• widening 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
• rebuilding the Old Big Bend Road and Big Bend Road bridges

Construction activities are estimated to finish in summer 2025.
