A semi-trailer rig toppled on wet Interstate 80 early Monday, closing down westbound lanes ahead of the morning commute.

About 5:30 a.m., with a cold drizzle making roadways slippery, the truck and its trailer had flipped onto their sides, blocking the freeway at mile post 136, near the Lambs Canyon exit.

There were no immediate reports of serious injury, and no other vehicles were involved in the crash.

UHP had the wreckage, and some of the truck's spilled load of frozen food, cleared away by 7 a.m. and reopened one westbound lane. The remaining lanes were reopened about an hour later, but traffic was backed up more than a mile and congestion reported to be heavy through the accident scene.

The cause of the accident was under investigation, but troopers reported that the truck appeared to have been traveling too fast for road conditions when it jack-knifed and overturned.
