- Pitkins Curve/Rain Rocks presents Caltrans with its toughest maintenance challenges in the central California coastal area.
This stretch of highway traverses the steepest coastal slope in the contiguous United States and is world-renowned for its rugged beauty," CalTrans wrote.
In 2000, a massive landslide below the highway at Pitkins Curve took out both lanes and closed Highway 1 for 30 days. Restoration required removal of 100,000 cubic yards of landslide debris in 7,000 truckloads.
ThePitkins Curve bridge is the only rock-shed bridge of its kind in the United States that was not built because of snowy weather.The rock shed is 239.5 ft long and 54.5 ft wide and with the bridge cost $39 million to build.
The design of the rock shed is the result of a back-and-forth process between Caltrans staff and a group of Big Sur residents called the Aesthetic Design Advisory Committee, said CalTrans project manager Rasmussen
