Stretch of I-15 southbound to close overnight this week in Las Vegas

A stretch of Interstate 15 near the resort corridor is set to shut to traffic overnight this week.

I-15 southbound between Spring Mountain and Flamingo roads will be closed from 10 p.m. Wednesday until 4 a.m. Thursday, the Department of Transportation announced Monday.

The Spring Mountain Road onramp to I-15 southbound also will close, from 9 p.m. Wednesday until 5 a.m. Thursday.

Motorists will be detoured to Spring Mountain, where they’ll head west to Valley View Boulevard, then south. Motorists will travel on Valley View Boulevard until they reach Flamingo Road, then east back to I-15 southbound.

The closure is needed for the installation of Active Traffic Management signs as part of Project Neon, a nearly $1 billion, 4-mile-long widening of I-15 from the U.S. Highway 95 interchange to Sahara Avenue that began in 2016, according to the department.

Project Neon is 92 percent finished and scheduled for “substantial completion” in July.
