State Highway 70 Safety Improvement Project


DESCRIPTION

The California Department of Transportation (Caltrans) is proposing a safety improvement project on State Route 70 (SR) in Yuba County near Marysville between Laurellen Road and the South Honcut Creek Bridge. The project need is based on a Traffic Accident Surveillance and Analysis System (TASAS) Report for the 3-year period between August 2010 and August 2013. This segment of SR 70 has had 85 reported collisions: including 7 fatalities, 32 reported injury accidents and the remainder being property damage only accidents. The number of fatal collisions along this section of highway was 3.8 times higher compared to the statewide average, qualifying this location for safety improvements. The proposed improvements are expected to reduce the collision rates at this location. Within the project limits there are: 136 driveways, 11 county roads, 7 private roads, and 22 farms/businesses. The school buses stop 26 times along SR 70 throughout the area to pick-up and drop-off school children.
