A connector from Interstate 805 to State Route 54 was closed after a tractor-trailor crashed into a pickup truck, causing a chain reaction collision, officials said.
A Sig Alert was issued for the area in Chula Vista around 1:30 p.m., California Highway Patrol officials said. All lanes reopened to traffic around 5:30 p.m.
CHP Sgt. Rick Rodriguez said the driver of the pickup truck suffered serious injuries, including lacerations to his face. His injuries are non-life threatening. Another person hit as a part of the chain reaction and suffered serious but non-life threatening injuries.
"We’re just happy at this point everyone is alive," Rodriguez said.
There was no word on what exactly caused the crash, though Rodriguez said their initial investigation showed the truck may have seen slowing traffic and been unable to stop in time.
