SAN LORENZO (CBS SF) — A big rig carrying hazardous materials has crashed on the ramp connecting northbound I-880 to southbound 238 near San Lorenzo, shutting down the connector according to authorities.
The crash was reported by CHP at around 11:22 a.m. when the big rig with a single trailer collided overturned on the left shoulder of the connector and starting a fire.
While the driver suffered only minor injuries and the fire was quickly put out by responding units, CHP officers determined that the big rig was carrying hazardous materials that were leaking on to the dirt on the shoulder, requiring that the entire ramp be shut down.
CHP told KPIX 5 they have also evacuated a Caltrans building just south of the crash.
The hazardous material leaking from the vehicle is glycol, a common ingredient in antifreeze.
Fremont and Hayward police also responded to the scene, according to authorities.
By about 3:45 p.m., authorities were working to put the trailer upright.
Motorists were advised to expect delays and to use alternate routes. Caltrans said it planned to reopen the roadway by 9 p.m. Wednesday night.
But as of 11 p.m. Wednesday, it remained closed.
