I-15, the primary highway serving the Las Vegas area, is currently undergoing a major reconstruction and improvement program that includes a widened freeway, new auxiliary roads designed to help traffic flow on the freeway, redesigned interchanges, 26 new bridge sections, 35 new retaining walls, and 1 1/2 miles of new sound walls. The $246 million project, scheduled for completion in early spring 2012, is being done under the auspices of the Nevada Department of Transportation, and funded through Assembly Bill 595, including funds diverted from room tax revenue and bonded through the Las Vegas Convention and Visitors Authority.

The project encompasses the stretch of Interstate 15 from Tropicana Avenue to just south of Silverado Ranch Parkway. The contractor for the design/build project is a team led by Las Vegas Paving Corp., Las Vegas.

Landscaping along the improved highway will embody the concept “Nature’s Residents,” celebrating wildlife and botanical diversity in custom designed graphics to be displayed along the corridor between Blue Diamond Interchange and Tropicana Interchange. Local wildlife will be portrayed as steel sculptures in murals on bridge walls. In addition, bridge walls at several locations will have abstract scenes cast into the concrete.
