Empty tank on trailer falls onto road

SAN DIEGO – A tractor-trailer rig overturned on Interstate 805 in Mission Valley tonight and an empty tank fell off the trailer and plummeted onto Camino del Rio South, authorities said.

No injuries were reported.

Fearing that the tank might have contained hazardous chemicals, San Diego police and the California Highway Patrol blocked lanes and closed the ramp from northbound I-805 to Interstate 8 after the 9:15 p.m. accident.

Police said they were told the tank was empty. Hazardous-materials crews and firefighters responded. Some diesel fuel spilled from the tractor, which had been pulling the flatbed trailer and tank on transition lanes from I-805 to I-8.
