Interstate Highway 580 has reopened following a full closure of the highway in both directions after a United Parcel Service big-rig crashed Friday morning in the San Quentin Prison area, the California Highway Patrol said.
The freeway fully reopened at 6:38 p.m., the CHP said.
One of the big-rig's two trailers, which contained 50,000 pounds of packages, caught fire, CHP Officer Andrew Barclay said.
"I saw a coffee table, books, shoes and clothing. We're not aware of any chemicals in the trailer," Barclay said.

The westbound big-rig struck and drove along the concrete center divider for about 400 feet around 5:26 a.m. spilling diesel fuel along the way, Barclay said.
The westbound lane was damaged during the crash, Barclay said.
The CHP tweeted out a picture of the big rig ablaze on the westbound side of Interstate Highway 580 near San Quentin heading into San Rafael. The big rig was carrying packages with "household goods," according to the CHP. The first trailer caught on fire, and the second trailer didn't suffer any damage, the CHP said.
The driver, who was not injured, said the big-rig started jerking before the crash, Barclay said. He is not believed to have been driving under the influence, and the CHP will investigate if he fell asleep, Barclay said.
Traffic was diverted around the crash site onto Main Street, then back on westbound I-580, the CHP said.
