An elevated section of Interstate 10 collapsed Sunday amid heavy rains in a remote desert area of California, cutting off traffic between the state and Arizona and leaving a driver injured.
The Tex Wash bridge in Desert Center, which carries the eastbound interstate about 15 feet above a normally dry wash west of the Arizona state line, snapped and washed away in flooding water below, the California Highway Patrol said.
One driver had to be rescued from a pickup truck that crashed in the collapse and was taken to a hospital with moderate injuries, the Riverside County Fire Department said. A passenger from the truck was able to get out without help and wasn't hurt.
"Bystanders quickly used straps from their trucks to secure vehicle to guardrail to prevent it from washing away," the Riverside County Fire Department officials said in a statement.
California transportation officials say the westbound side of the 10 Freeway has also been badly compromised by flooding in the same area where the eastbound side collapsed.
Caltrans spokeswoman Terri Kasinga said Sunday night that it means the interstate that serves as a main route between California and Arizona will stay shut down "completely and indefinitely."
Kasinga says engineers won't even be able to properly assess the damage to the two sides until Monday morning, and offered no timeframe for their opening again.
