Wave Breaker Construction and Shoreline Restoration Begins Along Pacific Coast Highway (SR-1)

Eroded slopes, looking west along PCH in Malibu
Caltrans will begin constructing a wave breaker (rock slope protection) and restoring the shoreline on the ocean side slopes of Las Tunas Canyon Beach along eastbound Pacific Coast Highway (SR-1) east of Big Rock Road on Wednesday, October 28.  The 1,600 foot-long and 20 to 30 feet-tall wave breaker will protect slopes and shoreline that were eroded by high tides that were caused by hurricanes in Mexico last September.  The erosion could potentially undermine the highway.  The project is expected to finish in April 2016.

Sea wall installed September 2014.
The majority of construction will be performed behind temporary concrete barriers.  When lanes closures are necessary, one lane in each direction will be closed between Pena Road and Big Rock Drive, during the day from 9 a.m. to 3 p.m., and if night work occurs, from 10 p.m. to 5 a.m., Monday through Friday.  The contractor expects to work Monday through Sunday.  Additionally, work hours and duration will be affected by the tide and possible El Niño related storms.

Motorists and residents should expect occasional delays on the highway and noise from heavy equipment and boulders being dumped to build the wave breaker.  The majority of work will take place behind concrete barriers along the highway and the construction area will be unavailable to cyclists and pedestrians.

To protect utility lines from large waves a smaller 50 foot-wide concrete wave breaker was constructed within the limits of this project last September. 

Project limits
Nordic Industries of Olivehurst, California was awarded this $8.2 million contract that is funded by the State Highway Operation and Protection Program.

Remember to Be Work Zone Alert.
