A tractor-trailer that jack-knifed on U.S. Highway 101 at North Shoreline Boulevard in Mountain View tied up traffic for about four hours, the California Highway Patrol (CHP) reported Thursday afternoon.
The accident occurred at 12:40 p.m. and was cleared at about 4:40 p.m.
The two right lanes northbound and the off-ramp were closed and drivers advised to avoid the area.
The CK Transport big rig from Lucerne Valley, Calif., was pulling two trailers filled with 73,000 pounds of lime when the driver was forced to take evasive action, on-scene CHP Redwood City Officer Curtis Glace said.
The rear trailer tipped over, Glace said.
The highway patrol is investigating the cause of the crash to determine if another vehicle might have been involved. Alcohol was not a factor and no one was injured, he said.
"At this point, we're not sure if another vehicle may have hit the truck or cut the driver off," Glace said.
A hazardous-materials team was called out as a precaution. Caltrans and the Mountain View Fire department were on scene during the cleanup to help prevent any long-term closures, he said.
