A roughly 1.4-mile stretch of California's famed Highway 1 between Big Sur and Carmel-by-the-Sea closed Saturday after yet another landslide that the Cal Trans didn't see coming, that could have been prevented with an excavator at work for a day

That slide happened 10 days after access to the south, in northern San Luis Obispo County, was cut off due to a slide on Jan. 4 at a location known as Polar Star, about a mile south of Ragged Point. 

In between those two slides, creating an "island," there was another major slide at Mill Creek, at mile marker 18.

Estimated reopening time (for one-way traffic): three to four weeks.
