PROJECT COST: $246.5 Million
This design-build project will widen Interstate 15 from Tropicana to just South of Silverado Ranch Boulevard. Work includes adding collector-distributor roads, re-designing three interchanges, adding a new Sunset Road Bridge over I-15, and widening the existing bridge at Warm Springs Rd. Work also includes building 24 new bridges, 35 retaining walls and 1.5 mi of sound walls. There will be approximately 8 mi of new asphalt roadway paving, and more than 100,000 cu yds of concrete. Extensive regionally themed aesthetics with drought-tolerant landscaping, colorful graphic designs and Cor-Ten steel sculptures round out the project.
