LOS ANGELES, Calif -
Nine big-rigs have collided in an Interstate 5 truck bypass tunnel in the Newhall Pass north of Los Angeles.
Rainy weather may be a factor in causing Tuesday morning's jumble in the tunnel 25 miles north of downtown.
A jackknifed big-rig in the tunnel apparently caused the chain-reaction crashes.
A Los Angeles news station says firefighters had to pry a trucker out of his demolished rig. He was extricated just before 6 a.m. and taken to a hospital.
The California Highway Patrol says the southbound, two-lane truck bypass tunnel will likely be closed until noon while wreckage is cleared and spilled diesel fuel is mopped up.
