I-15 Central Corridor
NEPA Study Project
Nevada Department of Transportation
Welcome to the I-15 Central Corridor National Environmental Policy Act (NEPA) Study project page. This NEPA study, currently underway, focuses on the I-15 Central Corridor from Flamingo Road to Sahara Avenue.
The project and study aim to integrate the I-15 Central Corridor with two previously completed I-15 widening and reconstruction efforts:
• I-15 South Design-Build- I-15 South from Blue Diamond Rd to Tropicana Ave
• Project Neon- Phase 1 from the Spaghetti Bowl to Sahara Ave
Initial planning for this project was completed in August 2021 with the publication of the I-15 Flamingo to Sahara Study. The project is now undergoing further development and refinement as part of this current NEPA study.
Current Project Activities
> Environmental Justice surveys are being rescheduled to a later date to be announced.
> Team is currently conducting one-on-one meetings with project stakeholders.
> NEPA Participating Agencies are providing input on project’s Purpose and Need.
About the I-15 Central Corridor Project
The existing I-15 Central Corridor has five through lanes in each direction, and fails to meet projected traffic demands, which will further delay travel through this segment.
Nevada Department of Transportation (NDOT) is proposing to address deficiencies along a 4.5-mile stretch of I-15 between I-215 (Southern Beltway) and Sahara Avenue. Improvements are being considered, in accordance with the project’s purpose and need to achieve.

Optimal operational efficiency and traffic capacity of I-15 and adjacent interchanges at Sahara Avenue, Spring Mountain Boulevard, and Flamingo Road
Matching the capacity of this segment with stretches of I-15 north of Sahara Avenue and south of Tropicana Avenue
Integrating other potential non-freeway road improvements adjacent to the interstate and new High Occupancy Vehicle (HOV) freeway access between Desert Inn and Sahara
Improved safety for motorists and pedestrians along the corridor including adjacent surface streets
The implementation of proposed improvements that serve planned future transportation needs
