2 dozen cars get flat tires on San Mateo Bridge

Two dozen cars get flat tires on the San Mateo Bridge.

Two dozen cars suffered flat tires early Wednesday morning when a 100-pound metal bar left in the road damaged their commutes on the San Mateo Bridge. 

The bar fell off a truck about 4:40 a.m., the California Highway Patrol reported. 

By 5:30 a.m., the bar had been removed but several tow trucks had been called.
