I-75 FROM SR 50 TO HERNANDO COUNTY LINE
Hernando County, FL
This $94 million Design-Build project to widen and reconstruct six miles of I-75 in Hernando County included reconstruction of the interchange at US 98/SR 50/Cortez Boulevard to a Single Point Urban Interchange (SPUI) configuration. The I-75 bridges over US 98 were replaced with single-span steel bridges designed to accommodate the future widening of I-75 and US 98. Approximately one mile of US 98 was widened and reconstructed within the interchange limits using concrete pavement. New high-mast lighting was designed for the interchange and signals at the ramp intersections. New ITS infrastructure was designed along I-75 and US 98. Utility Work by Highway Contractor plans were developed for relocation of Hernando County water and wastewater mains. The project included replacement of the guardhouse at the entrance to the Withlacoochee State Forest Croom Motorcycle Area. I-75 bridges over Croom Rital Road and Withlacoochee River were widened to accommodate new lanes. Other services included obtaining environmental permits, signing and pavement marking design, geotechnical investigation, gopher tortoise investigation and relocation, utility coordination, and public involvement.
