Las Vegas residents and visitors should prepare for overnight travel disruptions as the Nevada Department of Transportation (NDOT) has announced lane and ramp closures on Interstate 15. The I-15 South Widening Project, aimed at increasing the interstate's capacity, will see restrictions for pavement sealing, barrier rail improvements, and the installation of overhead signs. Affected areas include northbound lanes between Sloan Rd and Blue Diamond Rd, as well as southbound lanes from Blue Diamond Rd to Sloan Rd, with intermittent ramp closures expected, as per the NDOT announcement.

These closures are scheduled to occur nightly from 8:00 p.m. to 5:00 a.m., beginning Sunday, Oct. 19, and continuing until Friday, Oct. 24. Motorists are advised to take caution when traversing through work zones and consider detour routes to avoid delays. NDOT has coordinated with Waze to keep travelers informed about expected highway restrictions. However, they remind drivers that the schedule may change if weather or other unforeseen factors arise.

In a specific instance of closure, the eastbound Blue Diamond Rd flyover ramp to northbound I-15 will be inaccessible from 8:00 p.m. Wednesday, Oct. 22 to 5:00 a.m. Thursday, Oct. 23. Those who regularly use this route should plan ahead for this interruption. For further information on state highway conditions, the public can utilize resources such as nvroads.com or the NDOT hotline at (775) 888-7000 before hitting the road.
