Temporary lane to ease traffic on I-15 between Southern California and Las Vegas

Good news for drivers leaving Las Vegas.

Starting Sunday, Caltrans will open a temporary lane on southbound Interstate 15 from 10 a.m. to 8 p.m. on Sundays and Mondays to relieve traffic heading toward Southern California and away from Sin City.

Caltrans completed the first phase of the project, a transition lane that begins in the border city of Primm, Nevada, and crosses the California state line, in the fall of 2022. The agency has already finished renovating the highway's shoulder for periodic use. Additional roadside message boards will remind drivers when the shoulder is available for travel.

Busy I-15 is known for traffic jams during the holidays.

Following the 2022 Thanksgiving weekend, motorists returning to Southern California from Las Vegas had nothing but bad luck as traffic on the main route across the Nevada border was backed up for 16 miles.

The highway bottleneck began just south of Primm on the Nevada side of the border and added about an hour to the trip from Las Vegas to Ontario, California, officials with the Southern Nevada Regional Transportation Commission said.
