Over the next few months Caltrans will install 175-linear feet of rock slope protection on Surfers’ Beach as an interim solution (10-15 years) to reduce erosion and prevent collapse of Highway 1. The project includes paving a 400-foot section of the Coastal Trail along the west side of the highway and a staircase down to the beach.

Construction activities will occur between 7AM and 3:30 PM, although some night work may be required.  Minimal lane closures may take place. The pedestrian trail will be temporarily detoured. Construction is expected to be complete by Jan 2016.
