An overturned fuel tanker shut down northbound Interstate 680 in Fremont for hours Friday and forced some nearby residents to evacuate because of a fuel spill, according to the California Highway Patrol.
The crash occurred just before 5 a.m. Friday on northbound I-680 north of South Mission Boulevard, the CHP said.
The CHP closed all northbound lanes for hours and called a hazmat crew to the scene because of fuel leaking from the tanker. Two lanes reopened at about 2:45 p.m., and officials said a full reopening would happen at about 5 p.m.
Fremont police evacuated about 100 nearby homes as a precaution, and that order was lifted at about 2:20 p.m., the CHP said.

It was not immediately clear if there were any injuries in the crash.
The crash and closure also caused a traffic backup for miles. Fire crews estimated it would take 8-12 hours to offload the remaining fuel into another tanker and upright the trailer and tractor, according to the Fremont Fire Department.
