A big rig crash had Point Reyes-Petaluma Road closed down Friday afternoon at Hicks Valley Road, about halfway between the two commmunities that give the rural road its name.

The CHP said it might be about 4:30 p.m. before the wreckage was cleared and the highway fully reopened.

The crash occurred at 12:22 p.m. and may have involved a second semi, though details of the incident were unclear.

Additional information will be posted when it is available.
