Crews will reconfigure one direction of the highway to allow for both directions of travel.  Starting Friday, Aug. 9, one lane in each direction will remain open with a reduced speed limit of 45 mph.

The temporary changes will remain in place until crews build new bridges that carry US 101 over Griggs Creek. When work is complete, crews will move traffic back with two lanes open in each direction.
