LAS VEGAS – The Nevada Department of Transportation is proud to announce that the I-15 South Design-Build Project received the major project of the year award in the over $20 million category from the Nevada chapter of the American Public Works Association at its fall conference in Lake Tahoe, Sept. 26-28. Projects nominated for APWA awards are evaluated on the basis of service to the public, community need, intricacy of design, aesthetic consideration, difficulty of construction, cost growth and time growth and complexity of financing.
The $246.5 million project involved collaboration between NDOT, the Las Vegas Convention and Visitors Authority, Clark County and the Regional Transportation Commission. The project was primarily funded by bonds issued by the LVCVA, which agreed during the 2007 Legislature to commit funds to transportation projects in the resort corridor. The county provided funding for Sunset Road from Las Vegas Boulevard to Valley View Boulevard, including a bridge over I-15. Throughout the project’s 30-month construction schedule, the RTC provided crucial traffic control coordination via the Freeway Arterial System of Transportation system. Las Vegas Paving served as general contractor. Project goals included creating a safer, more efficient I-15 commute from Tropicana to Silverado Ranch and providing easier access to Strip properties and McCarran Airport.
Components of the six-mile project included widening the freeway, adding northbound and southbound access roads, redesigning five interchanges and building 26 new bridge sections, 35 retaining walls as well as sound walls. Other features include Intelligent Transportation System infrastructure to improve traffic flows, landscape and aesthetic enhancements, steel sculptures of indigenous animals (sheep, coyotes, horses, burros, hawks and reptiles) as well as native plants and desert-adapted seeds, which require minimal water and no long-term irrigation. At its zenith, the project provided more than 400 jobs.
In design-build projects, final phases of construction are often designed at the same time as earlier phases are built, reducing both project length and cost. In addition, both design and construction are contracted with a single contractor, minimizing project risk and offering greater project innovation and collaboration. In March, NDOT was named “Transportation Owner of the Year” in the southwestern United States by Engineering News-Record/Southwest magazine for the I-15 South Design-Build, West Mesquite Interchange Design-Build, I-80 Design-Build and the I-15 North Design-Build projects.
Established in 1917, the Nevada Department of Transportation is responsible for the planning, construction, operation and maintenance of 5,400 miles of highway and more than 1,000 bridges comprising the state highway system. NDOT’s mission is to provide a better transportation system for Nevada through unified and dedicated efforts. The department is divided into three districts. The districts are responsible for supervising all state transportation activities within their local areas. NDOT’s headquarters is located in Carson City; district offices are in Las Vegas, Reno and Elko. NDOT is overseen by a seven-member directors’ board and run by senior staff.
