Firefighters from San Francisco responded. Officials shut down all traffic so firefighters could drive the wrong way on the westbound upper deck to get to the fire. While they made their way to the emergency -- propane tanks on the truck exploded. There were at least three different bursts between 8:25 and 8:40 this morning.
Caltrans said it opened all lanes of the bridge at 1 p.m.
During an inspection, Caltrans engineers determined that the bridge was structurally safe, however, the asphalt would need to be replaced due to concerns over the longevity of the pavement.
Three people were in the vehicle but no injuries have been reported.
The cause of the fire is under investigation.
