A vehicle fire shut down a lane on westbound Interstate 10 in Beaumont Monday, worsening already bad traffic as motorists return from the Labor Day weekend.
The gridlock extended for about 25 miles all the way to Palm Springs by 1 p.m., according to Sigalert.com.
The No. 1 lane at Pennsylvania Avenue was blocked due to a vehicle catching fire and becoming fully engulfed at about noon, according to the California Highway Patrol.
Riverside County firefighters responded and extinguished flames, but the closure remained in place.
