Document Description
The proposed project would improve safety on a curve on State Route 20 in Mendocino County. The project is being proposed due to a high collision rate at this location. After a 1998 storm event, it is believed that a large landslide caused a shift in the roadway alignment, which resulted in the existing compound curve. A 3-year traffic safety analysis between January 01, 2014 and December 31, 2016 determined that collision rates between post miles 20.08 and 20.3 were 6.8 times the state average for similar facilities.
Work would realign the compound curve into a single curve, widen and pave existing shoulders, install a gabion wall, extend an existing culvert, grind and remove existing concrete, place shoulder backing, apply a hot mix asphalt overlay, install centerline and shoulder rumble strips, and restripe the roadway. Geotechnical drilling during the Design phase would determine the final placement of the gabion wall and culvert extension. All project work would occur in the Caltrans right of way. Air Quality, Biological, Cultural, Hazardous Materials, Noise, Visual, and Water Quality reviews have been completed.
