Interstate 65 Widening
Robertson CountyThe 9.68 mile project for Interstate 65 (I-65), from near State Route (SR) 25 to near SR consists of widening the roadway to six total lanes, replacing 10 bridges and four overpasses, building 17 retaining walls, adding ITS throughout the corridor, and converting the northbound weigh station into truck parking. The planned improvements are designed to improve capacity and operation of I-65. The project will:
· Improve the capacity and operation of the I-65 corridor
· Improve drainage and stabilize subsurface issues
· Replace deficient bridges
· Repair damaged concrete pavement on ramps
· Increase deceleration lanes for off ramps
· Provide truck parking area
· Provide additional clearance for potential future widening of I-65
This $160 million project is the largest in TDOT history.
