WGI teamed with Middlesex Corporation to deliver this $94M Design-Build project to widen and reconstruct six miles of I-75 in Hernando County. The project includes 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 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 were replaced at the ramp intersections. New ITS infrastructure was designed along I-75 and US 98. Utility Work by Highway Contractor (UWHC) plans were developed for relocation of Hernando County water and wastewater mains. The project includes 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. WGI secured environmental permits from SWFWMD and USACE.
Other services include signing and pavement marking design, geotechnical investigation, Gopher tortoise investigation and relocation, utility coordination, and public involvement.
