The Nevada Department of Transportation (NDOT) is announcing an updated schedule of lane closures on Interstate 15 (I-15) for the ongoing I-15 South Widening Project. Significant travel delays are expected, particularly on northbound I-15 between Silverado Ranch Boulevard and Blue Diamond Road, where a continuous auxiliary lane closure will be in place through July. Drivers are encouraged to plan ahead, allow extra travel time, and consider alternate routes when possible.

These traffic restrictions are necessary for guardrail repair, roadway excavation, and paving operations. The schedule is subject to change due to weather and other factors.
