At least one car crashed into a pole early Tuesday, forcing the partial closure of a road that runs from Antioch to Concord, the California Highway Patrol said.

The wreck on Marsh Creek Road happened around 5:15 a.m. near the Deer Valley Road intersection, CHP Officer Ron Simmons said. Two cars were involved in the wreck, but it was not known immediately if both crashed into the pole, he said.

Officers initially thought one of the cars had knocked over an electrical pole and the driver was believed to be trapped inside. But PG&E later advised that the pole knocked over was a utility pole, and the driver was able to exit the car, he said.

Nobody was injured, Simmons said.

Marsh Creek Road was expected to be closed in both directions for several hours while repair crews replaced the pole and cleaned up debris. Vehicles traveling on the road were being turned around at the scene and forced to go back in the direction from where they came, Simmons said.
