SH360 Tollway

REL served as the Independent Construction Quality Assurance Firm (ICQAF) on SH 360 South Tollway south of I-20 to US 287 in Tarrant County, Mansfield, TX.

The Project

This $340 million project added two toll lanes in each direction from approximately two miles south of I-20 near East Sublet Road/West Camp Wisdom Road to US 287. In addition, the project provided intersection enhancements and frontage road improvements that deliver continuous non-tolled frontage roads throughout the corridor. The project also added US 287 north and southbound main lane bridges over SH 360 and a portion of the US 287 northbound frontage road and ramps. The project was constructed through a design-build approach providing needed safety improvements, congestion relief and economic development benefits.
