Motorists making their way west as they return from the holiday weekend were facing gridlock Sunday on Riverside County freeways.
Traffic was moving under 20 mph on parts of westbound Interstate 10 through the San Gorgonio Pass, the main connector between the Los Angeles Basin and the Coachella Valley, according to Sigalert.com.
Speeds were even slower on the westbound State Route 60 through the so-called Badlands area, east of Moreno Valley, where traffic was reduced to one lane due to ongoing construction.
