LOS ANGELES (CBSLA.com) — As many as 15 cars had their tires flattened early Wednesday after hitting a pothole on the northbound San Diego (405) Freeway in the Sepulveda Pass.

The problem was reported around 7:45 p.m. Tuesday at Mulholland Drive near Skirball Center Way, said CHP Officer Anthony Martin.

Vehicles were lined up along the side of the road as drivers waited for tow trucks or help changing their tires.

It was unclear what caused the pothole, but aerial video showed what appeared to be a square cavity in the road.

Caltrans crews worked through the night and repairs to the hole were completed by early morning, Martin said.
