About the NEPA Study
As a part of the I-15 Central Corridor Project, NDOT is evaluating potential improvements to address a congested segment along Interstate 15 within the resort corridor area.
In 2009, the Nevada Department of Transportation (NDOT) embarked on the I-15 Design-Build South project, which widened the freeway between Blue Diamond Road and Tropicana Avenue. A subsequent endeavor, Project Neon, widened I-15 between the Spaghetti Bowl and Sahara Avenue.
The I-15 segment between the Project Neon and I-15 South Design Build project footprint has become congested as there are fewer lanes to accommodate the number of vehicles traveling along the Interstate.
Project Details
The existing I-15 Central Corridor only has five through lanes in each direction, and fails to meet future projected traffic demands, which will further delay travel through this segment. NDOT is working to address these deficiencies by evaluating possible improvements that will optimize the operational efficiency and traffic capacity of I-15, as well as its adjacent interchanges with Sahara Avenue, Spring Mountain Road and Flamingo Road.
Need
• Existing roadway deficiencies need to be resolved
• Transportation improvements to serve existing and future growth areas need to be identified
• Potential improvements need to be coordinated with regional and local plans
Benefits
• Future I-15 improvements in this area will improve safety for drivers and pedestrians
