A large platform carrying 27 tonnes of concrete sand spills onto SB I-680

PLEASANTON, California (KGO) –

A large platform carrying 27 tonnes of concrete sand spilled on the south lanes of I-680, near Bernal Avenue in Pleasanton.

According to the CHP, a newer white Honda Civic swept the big platform before 5am, forcing the driver to turn around and sign a black chord.

The driver of the agreement was hospitalized.

The driver of the big truck then hit a guardrail, overturned and dumped his cargo on several tracks heading south.

Israel Gonzalez was driving. He was carrying tons of cement sand up to Fremont when he was swept to the side. Gonzalez was able to get out of the accident without hurting himself.

"I'm really lucky because I'm still alive, you can see my truck," Gonzalez told ABC7 News. "I feel really, really bad because you know, because I do not want to hurt anyone."

The accident and sand spill into the concrete resulted in heavy traffic at the start of the Friday morning commute.

The CHP said the Civic driver had been involved in a hit and run with a silver Infiniti to the north near Stoneridge. The Infiniti then began following the Honda Civic heading south on the I-680, according to authorities.

A witness reported that two vehicles drove imprudently in front of the Civic sweeping the large platform, officers said.

"There is about a mile and a half between the scene of the crash and that of Stoneridge," said Kevin Johnson, PSC agent, at ABC7 News. "The initial hit-and-run accident was not related to that."

Officers connected with the driver of the Infiniti.

Authorities continue their search for the Civic pilot, wanted for offense.

Two lanes have been reopened and all lanes are expected to reopen at 1 pm
