The California Highway Patrol closed southbound state Highway 680 near Sunol for five hours Friday due to a traffic accident involving a big-rig tanker truck leaking fuel.
At 8:47 a.m., CHP officers responded to a report of a big-rig truck blocking the highway's southbound slow lane, just south of Andrade Road, according to CHP officials. The truck apparently hit a tow truck along the highway, which then caused it to leak ethanol, CHP officials said.
Fire crews arrived on scene at about 9:10 a.m. to assess the spill. They then called a hazmat team, according to the CHP. At 9:43 a.m., the CHP issued a Sig-alert for the highway, closing all the southbound lanes and advising drivers to exit at Andrade Road and take alternative streets.
At 10:06 a.m., the CHP decided to close the highway's southbound lanes at state Highway 84. Additionally, the CHP also closed eastbound state highway 84 to southbound state Highway 680.
Southbound lanes of I-680 reopened by about 3 p.m. CHP said another tanker truck had to be brought in to offload the fuel from the leaky big-rig.
