- Document Description
- The California Department of Transportation (Caltrans) proposes to improve two non-contiguous segments of the alignment of State Route (SR) 20 in Nevada County between post miles (PM) 29.7-30.9 and 36.8-39.8 by modifying the existing horizontal and vertical curves of the roadway and adding turnouts. This project will update the roadway to current standards by increasing the curve radii, widening shoulders to 8 feet, adding turnouts for both directions, and improving the vertical profile grade. Additionally, this project will improve the clear recovery zone (CRZ) by removing obstacles and flattening slopes close to the traveled way. Two main project segments occur between PM 29.7-30.9 and 36.8-39.8 are referred to as White Cloud and Lowell Hill segments respectively.
