CONCORD -- A gravel truck spilled its load while on Highway 242 early Thursday morning, forcing one lane to be closed and creating a traffic headaches for commuters, a California Highway Patrol officer said.

The spill occurred about 6 a.m. in the northbound direction on the connector to westbound Highway 4, the officer said. Several vehicles spun out as a result of the spill, and Caltrans workers were required to clean up the gravel, the officer said.

A minor two-car crash that did not injure anyone occurred as a result of the gravel on the road, further slowing down the commute, the officer said.

The lane was reopened just before 8 a.m.
