FREMONT (CBS SF) — A cement mixer truck overturned on northbound Interstate Highway 880 in Fremont Wednesday afternoon, spilling some cement onto the highway and blocking multiple lanes for over three hours, a California Highway Patrol officer said.

The crash between the truck and another vehicle was reported shortly after 12:06 p.m. on northbound Highway 880 near the on-ramp from Thornton Avenue, CHP Officer Eric Anderson said.

Minor injuries were reported in the crash. Some cement spilled from the truck onto the highway and the three left lanes are blocked as of 1 p.m. while crews work to clear the scene and get the truck upright, Anderson said.

Video shot by KPIX 5 Sports anchor Vern Glenn shortly before 2:20 p.m. as he rode by the scene showed crews and CHP working to move the truck off to the shoulder, but two left lanes remained closed as a tow truck worked to right the vehicle.

All lanes were finally reopened at 3:30 p.m., according to CHP.  However, residual delays from the lane closures show that northbound traffic on I-880 was still slow with a back-up stretching all the way to Milpitas as of 5 p.m.
