That same year, California did the same for a one-mile span just south of the border.

That timeline didn’t quite pan out, though in 2022 Nevada did add a permanent third lane along the half-mile stretch between the Primm exit and the state line. The joint-state initiative was first announced in December 2021, with work set to begin in the spring of 2022 and wrap up by the end of that summer. The lane will be available to use every Sunday and Monday from 10 a.m. The I-15 Part-Time Lane will open this Sunday, Aug 27 for use. Paired with some permanent third-lane additions just to the north, this now effectively eliminates the two-lane bottleneck on this notoriously backed up part of the freeway (which, make no mistake, will probably still continue to see some pretty terrible traffic).ĪTTN I-15 CA and NV border commuters. According to Caltrans, as of August 27, the shoulder will now be open to drivers on Sundays and Mondays from 10am to 8pm. But some relief has finally arrived.Ībout a year after it was initially supposed to open, California has finished a part-time extra lane on the southbound 15 freeway just south of the Nevada border. That’s because three southbound lanes of the freeway historically narrowed down to two near the border town of Primm, causing hours-long backups until it went back to three lanes a few miles south of the California-Nevada state line. The traffic backup on the 15 freeway leaving Las Vegas can be an unmitigated nightmare, the sort of jam that has you wondering whether you should dare attempt to drive on a parallel dirt road and if your car can even handle it (no and no). But for us, there’s one decision that’s truly the most regrettable: choosing to drive back from Vegas to L.A. on a Sunday or Monday morning. The extreme late-nights and excessive booze may leave you second-guessing some of your choices after a weekend spent in Las Vegas.
