I-15-Tropicana aerial

I-15/Tropicana Avenue Interchange
Las Vegas, NV

Client: NDOT
Partner: CA Group

The Nevada Department of Transportation (NDOT) was awarded a $50 million Infrastructure for Rebuilding America (INFRA) grant for the I-15/Tropicana Avenue Interchange project that will improve vehicle capacity and add carpool lanes. Parametrix supported NDOT’s in submitting the grant application, assisting with technical writing, grant requirement quality assurance and quality control, and performing the benefit-cost analysis.
This segment of I-15 runs parallel to the Las Vegas Strip, with Tropicana serving as one of the primary access points used by tourists, taxis, freight, local residents, and Resort Corridor employees. Without these improvements, both I-15 and Tropicana Avenue would continue to incur severe congestion resulting in negative impacts to motorists and critical freight traffic, degrading the reliability to move people and goods through the region. The much-needed interchange reconstruction project will reduce congestion, decrease travel delays, eliminate conflicts between through and local traffic, and improve air quality.
