The existing two-lane conventional highway will be replaced with a two-lane access-controlled expressway. The project includes approximately 328,000 cubic yards of roadways excavation, 74,000 cubic yards of rock excavation, asphalt concrete dike, guardrail, drainage improvements, creek realignment, fencing, signing, and pavement delineation.
