Jackknifed big rig creates massive delays on northbound I-680

PLEASANTON  -- A big rig jackknifed in rain-soaked northbound lanes of I-680 near Sunol early Tuesday, forcing a two-hour shutdown that triggered an East Bay backup stretching for miles.

According to the California Highway Patrol, the crash took place around 4:10 a.m. between the Calaveras Road and the Pleasanton/Sunol Rd exit.

By 4:25 a.m., the northbound lanes were shut down and a Sig Alert was issued.  Traffic was diverted off the freeway. 

It took more than an hour for a heavy duty tow truck to make its way to the crash scene and to right the truck.

Two northbound lanes were reopened at 6 a.m.  There was no ETA as to when the other lane would be reopened.

No injuries were reported.
