Erosion closes Great Highway 

After a decade of anticipation, erosion has prompted the closure of the Great Highway south of Sloat Boulevard this morning and now it’s time to use the backup road that was paved in 2003.

Around 9 a.m. Department of Public Works officials decided it was time to close both southbound lanes of the 650-foot stretch after inches of rain ate away at the sand at its base, threatening its stability.

Earlier this month DPW closed just one lane of traffic, but both the lanes are now too questionable.

DPW started annually maintaining the stretch that has been problematic and prone to losing its base since the 1999 El Nino storms, and have anticipated this happening.

In 2003 workers paved a road parallel to the southbound lanes, and it’s being used as the backup plan for the first time today.

On Friday, DPW declared an emergency to accelerate replacing the sand at the highway’s base, but that has not started yet.

For five years, the DPW has been planning with the Golden Gate National Recreation Area and other agencies to possibly build a sandbar in the ocean to muffle the waves before they break at shore. However, it will take at least a year before anything happens on this project, GGNRA officials have said.
