California Famous Highway 1 Reopened After Massive Landslide in 2017

After more than a year California’s famous State Route 1 reopened on Wednesday, said the California Department of Transportation (Caltrans).

State Route 1, an icon in the Golden State, has breathtaking ocean views at Big Sur. On May 20, 2017, the highway was closed due to a massive landslide that happened near Big Sur.

The landslide destroyed part of the highway and at the same time created 15 acres of new land in the ocean and 9 miles of coastline.


In order to restore Highway 1, Caltrans started the $54 million project to build a new road on top of the debris.

This restoration project also gave USGS a new opportunity to do some remote sensing research. They used satellite pictures to create a time-lapse video, which shows the process of the project.

After 14 months, the iconic highway was open to traffic on July 18 at around 10 a.m.
