ANTIOCH -- The driver of a cement truck needed to be freed with hydraulic tools but was otherwise OK after his overturned over on westbound Highway 4 Saturday morning, authorities said.
The wreck at 7:25 a.m. near the Contra Loma Boulevard exit forced the California Highway Patrol to shut down all lanes in the westbound direction for nearly four hours, backing up traffic for miles, Officer Eric Anderson said.
Paramedics from the Contra Costa Fire Protection District freed the driver, Capt. Robert Marshall said.
According to Anderson, the cement truck collided with another car. Moments later, Anderson said, a third car crashed into a median near the crash scene. The CHP did not say whether the first crash caused the second one.
Only the cement truck driver suffered injuries, and they were minor ones, Anderson said.
Traffic was diverted onto A Street during the highway closure. All lanes reopened around 11:15 a.m.
