I-15 South Project: Sloan Road to North of Warm Springs Road
Construction underway through December 2025
Project Overview
The Nevada Department of Transportation (NDOT) began improvements along nearly nine miles of Interstate 15 (I-15) South from Sloan Road to north of Warm Springs Road in January 2024. This Project will aid in improving travel-time reliability, serve proposed growth in the area by increasing local mobility and access, and enhance I-15’s operational efficiency. Construction is anticipated to be completed within a 24-month period.
Project features include:
- Widening I-15 from six to eight general-purpose lanes between Sloan Road and St. Rose Parkway
- Widening and restriping I-15 from six to 10 general-purpose lanes between St. Rose Parkway and Blue Diamond Road
- Adding a High Occupancy Vehicle (HOV) lane in each direction between St. Rose Parkway and Blue Diamond Road
- Resurfacing bridges and pavement preservation at the Blue Diamond Interchange
- Construction of 6 new sound walls near qualifying residential areas throughout the corridor
Project Cost and Funding
The total cost for construction is $86 M. The project is paid for with 95% federal and 5% state funds. Funding sources include National Highway Performance Program (NHPP), Surface Transportation Block (STBG) and PROTECT Program grants, and state gas tax.

Project Background
In 2008, an Environmental Assessment (EA) was prepared for the I-15 South Corridor Improvement Project, addressing the environmental effects of improvements along the I-15 corridor, including a portion of Las Vegas Boulevard South, between Sloan Road and Tropicana Avenue. A Finding of No Significant Impact (FONSI) for the overall project was approved by the Federal Highway Administration on April 20, 2009.
In 2022, a reevaluation of the I-15 South EA and FONSI was done to consider changing conditions and new issues that have transpired over the last several years within the I-15 South project area. The reevaluation of effects of the Phase 2 improvements was approved by FHWA and the project immediately moved forward into design. Design plans were finalized in the summer of 2023.
