The Florida Department of Transportation (FDOT) is reconstructing the interchange at I-75 and US 301. The proposed improvements include reconfiguring the existing interchange as well as enhancements to three intersections along US 301: 51st Avenue East, 60th Avenue East, and 19th Street East, and adding auxiliary lanes from SR 64 to the new ramps.
The scope of this project is to widen the I-75 (SR 93) facility and reconstruct the I-75 (SR 93)/US 301 (SR 43) interchange from a partial cloverleaf interchange to a tight diamond configuration. New bridges will be constructed over the Manatee River for a northbound exit ramp and a southbound entrance ramp. They will be compatible with the ultimate section for future mainline traffic. The widening and reconstruction of I-75 (SR 93) will provide for an eight-lane divided roadway with 12-foot inside and outside shoulders (10-foot paved) and a median that varies from 64 feet to 161 feet. A depressed median with roadside ditches will be used to convey storm water.
The redesign of the I-75/US 301 interchange will not only handle the existing six lanes of traffic more efficiently, it will accommodate up to ten lanes (two express lanes and three general use lanes in each direction). These future ultimate improvements are planned to extend the acceptable level of service for I-75 well beyond 2050.
