State Highway 70 Safety Improvement Project


DESCRIPTION

The California Department of Transportation (Caltrans) is proposing a safety improvement project on Highway 70 in Yuba County near Marysville between Laurellen Road and the South Honcut Creek Bridge. There have been a higher number of fatal collisions along this section of highway compared to the statewide average, qualifying these locations for safety improvements. The proposed improvements are expected to reduce the collision rates at these locations.

PROJECT BENEFITS

The location of the project is in Yuba County between Laurellen Road and the South Honcut Creek Bridge, Post Mile (PM) 16.2/25.8 (9.6 miles), work would include:
  • Widening and paving shoulders to 8’
  • Providing a continuous 14’ two-way left-turn lane
  • Providing a 30’ Clear Recovery Zone (CRZ)*
  • Installing rumble strips on the shoulders and centerline
  • Straightening horizontal curves (increasing the curve radius)
  • Flatten vertical curves (increasing the length)
  • Widening and paving local road intersections to accommodate truck turning movements
  • Reconstructing driveways
  • Replacing or extending culverts as needed
  • Placing an asphalt concrete overlay
  • Constructing bio-swales and bio-strips to treat storm water runoff
  • Relocating utility poles
*The CRZ begins at the edge of the travel lane. The CRZ includes the 8’ shoulder and an additional 22’ beyond the shoulder that is cleared of fixed objects (utility poles, trees, ditches etc.).

FUNDING BREAKDOWN

The total cost is estimated at $101.7 million in federal and state funds.
