I-75 FM SR 37 TO CR 246/KINARD BRIDGE RD - PHASE I

complete

Project NH-75-1(205) is the widening and reconstruction of I-75 from two lanes in each direction to three lanes in each direction from just north of the SR 37 interchange to just north of the CR 246/Kinard Bridge Rd. interchange, for a total of 9.5 miles. Overpass bridges in the project corridor will be replaced on this project. The proposed typical section calls for 3-12' travel lanes in each direction separated by a concrete median barrier with 12.75' inside paved shoulders and 16' (14' paved, 2' grass) outside paved shoulders. The front slopes are 18' at 6:1 followed by a 4' flat bottom ditch and 2:1 back slope. The existing concrete pavement is to be removed and replaced with new full depth concrete. This project was designed with a 70 mph speed design.
