Western Association of State Highway and Transportation Officials Winners
1) On Time/Medium Project
New Mexico Department of Transportation
The San Mateo Interchange Project in central New Mexico involved the replacement of two interchanges and the resurfacing and widening of 1.4 miles of interstate. Construction time was slashed from 540 to 390 calendar days. With this, the I-40 widening and San Mateo Interchange was completed ahead of time, saving the community a year of inconvenience, over $140 million in road user costs, and $2 million to $5 million in traffic control costs.
2) On Time/Large Project
Nevada Department of Transportation
The I-15 Las Vegas Design Build project was the first such project in the state’s history. Completed 20 months early, the project located north of the Las Vegas Strip added four interchanges, along with bridge structures, lighting, landscaping, sound walls, and intelligent transportation systems.
3) Innovative Management/Small Project
Washington State Department of Transportation
The Nile Valley Landslide Prevention Project used innovative management to respond to a massive landslide that destroyed a half-mile of State Route 410 in October 11, 2009. The project involved re-channeling a river away from the landslide, monitoring for additional landslides, and the design and construction of a 4,000-foot detour road that could withstand anticipated winter floods. WSDOT and an emergency contractor worked 14 hours a day, seven days a week to construct a new river channel.
