I-15 near Las Vegas Strip gets back-to-back, full-weekend closures

The massive reconstruction of the Interstate 15-Tropicana Avenue interchange is almost done — but not before back-to-back weekends of major freeway closures.

Crews will repave and restripe stretches of the busy freeway as part of the yearslong, $382 million project. The repaving will mark the final major disruptions to mainline I-15 tied to the Tropicana interchange project, which began in 2022.

The first closure will run from 9 p.m. Friday to 5 a.m. Monday on I-15 northbound between Russell and Flamingo roads, according to the Nevada Department of Transportation.

During the closure, the following freeway ramps will also be closed to traffic:

— 215 Beltway westbound to I-15 northbound ramp; 215 eastbound to I-15 northbound ramp.

— Russell on-ramp to I-15 northbound.

— Tropicana on-ramp to I-15 northbound.

— Las Vegas Boulevard to I-15 northbound on-ramp.

During the I-15 northbound closure, motorists can take a detour by exiting the freeway at Russell and heading west to Decatur Boulevard. At Decatur, drivers should head north to Flamingo Road. There, motorists should head east on Flamingo to the I-15 northbound on-ramp.

The following weekend, I-15 southbound will be closed to traffic from 9 p.m. July 18 to 5 a.m. July 21 between Spring Mountain Road and Tropicana.

— During the I-15 southbound closure the following freeway ramps will also be closed:

— Spring Mountain I-15 southbound on-ramp.

— Flamingo I-15 southbound on-ramp.

— Harmon Avenue I-15 on-ramp.

During the I-15 southbound closure, motorists can take a detour by exiting the freeway at Spring Mountain, then heading west to Decatur. Drivers can then head south on Decatur until they reach Tropicana, where they’ll head eastbound. Motorists can then re-enter I-15 southbound at the Tropicana on-ramp.

Once the repaving and restriping work is completed on each section of I-15, the high-occupancy vehicle lanes that were temporarily removed will go back into effect.

The project saw I-15 widened by one lane in each direction between Hacienda and Harmon avenues; the Tropicana bridge widened over the interstate; upgrades and widening to Tropicana on- and off-ramps; the addition of the Harmon half-interchange, the reconfiguration of Dean Martin Drive at Tropicana; and the addition of Joey Bishop Drive.

Remaining work on the project includes widening Tropicana between Polaris Avenue and Valley View Drive. That work is expected to finish this fall. Some future on- and off ramp closures, I-15 lane restrictions and neighboring surface street impacts tied to the project are expected over the next few weeks.
