OAKLAND — A massive tanker truck fire following a car crash has prompted authorities to shut down all lanes of southbound Interstate 880 this morning, the California Highway Patrol said.

A vehicle struck the center divide about 6:15 a.m. near 16th Avenue, and soon after a rig carrying gasoline struck that vehicle, causing a tank of about 8,600 gallons of fuel to spill and catch fire.

A total of three vehicles were involved, according to the Oakland Fire Department. Three people suffered minor injuries but refused ambulance transport.

Southbound I-880 has been shut down at 16th Avenue, and the CHP is advising motorists to take alternate routes — primarily I-580 — to get around the crash site. Truck traffic is also being directed to I-580.
