I-80 Rockfall Protection
Caltrans is proposing to stabilize the cut slope along Interstate 80 westbound to prevent rock fall onto the interstate. The existing cut slope has continued to erode, with materials falling onto the shoulder and into the traveled way. The proposed improvements are located at three separate locations just west of the California-Nevada state line in Nevada and Sierra County. This project will include flattening existing slope, installing drapery system, constructing a concrete barrier, and constructing concrete valley gutter.
This project is needed to reduce rock fall from the cut slopes at both project locations, which enter the roadway and require mitigation by maintenance workers. Materials that fall along the slope need to be controlled and captured to prevent them from encroaching onto the highway and to minimize maintenance operations.
The proposed roadway protective betterments project is funded from the 2018 SHOPP (Fund 20.XX.201.150).
