This corridor improvement Design-Build project focused on existing 14-miles of congestion. The scope of work focused on a 6-mile segment extending from the SR-241 toll road to SR-91, incorporating major upgrades to the I-15 Freeway Corridor. The primary objective was to alleviate persistent daily traffic congestion and improve overall traffic flow and mobility throughout the region.
