traffic.transit.jpg11:45 AM: All lanes of eastbound Interstate Highway 80 in San Francisco are back open after crews removed a disabled big-rig and the portable building it was carrying that blocked the roadway for more than four hours this morning.

The big-rig and its load were relocated to the Fifth Street on-ramp in an unmarked area where the lanes merge, California Highway Patrol Officer Peter Van Eckhardt.

“It’s still on the road, but it’s out of the way of traffic,” he said.

Crews are having trouble removing the portable building from the highway because of its size, Van Eckhardt said.

“The trailer was in such bad shape. It’s an unusual load to move,” he said.

The No. 2 and No.3 lanes just west of Seventh Street had been closed since about 6:30 a.m., when the CHP issued a Sig-alert. The Sig-alert was canceled just before 11 a.m.

It is not clear why the big rig driver lost control but Van Eckhardt said it might have been because of a flat tire.

8:33 AM: A disabled big-rig and the portable building it was hauling are blocking two lanes of eastbound Interstate Highway 80 in San Francisco this morning, according to the California Highway Patrol.

The No. 2 and No. 3 lanes just west of Seventh Street are closed as the CHP and Caltrans work to remove the big-rig and its load, CHP Officer Peter Van Eckhardt said.

A second big-rig is headed to the scene to remove the portable building, but it is not expected arrive before 8:30 a.m., he said.

With only one lane of traffic open, the CHP is advising motorists to find an alternate route. Motorists headed to the East Bay are advised to use the San Mateo Bridge instead.

Van Eckhardt said the big-rig’s driver apparently lost control around 6:20 a.m. It is not clear why, but Van Eckhardt said the truck might have had a flat tire. A Sig-alert was issued at about 6:30 a.m.
