Deadly, Multi-Car Crash Blocks Westbound I-80 Traffic in Sierra

CISCO GROVE -- A deadly, multi-car crash has completely blocked westbound traffic on I-80 near Cisco Grove.

According to the CHP, as many as 16 cars were involved. Investigators say one driver was going too fast as hail was falling in the area, which caused a chain reaction crash.

At least one person was killed. A number of other people were taken to the hospital, but the extent of their injuries were not immediately known.

Drivers were encouraged to avoid the area for much of Thursday. The crash was cleared by mid-afternoon, but Caltrans warned of low visibility.
