State Route 70 Safety Improvement and Passing Lanes Project – Yuba County

Latest Construction News

YUBA COUNTY (May 4, 2022) Caltrans reminds motorists to be alert for construction equipment and crews working at various locations along the 9-mile stretch of State Highway 70 between Laurellen Road and the Yuba-Butte County line.

Motorists also should be watch out for flaggers handling intermittent traffic control along the corridor as well as large orange traffic drums placed along the shoulder of the roadway.

Over the next two years, contractor DeSilva Gates Construction of Dublin, Alameda County, will be working at various locations during day and nighttime hours Monday through Saturday. Motorists should allow additional travel time and may expect intermittent traffic-interfering work, especially during overnight hours.

Residents in the area may hear loud construction noise, including OSHA-required vehicle backup warning alarms. The contractor will maintain access to all driveways and cross streets during construction.

Caltrans reminds motorists to “Be Work Zone Alert” and that the construction zone speed limit has been reduced to 45 mph between Laurellen Road in Yuba County and East Gridley Road in Butte County, where a separate construction project is underway.

Description

The location of the project is in Yuba County between Laurellen Road and the South Honcut Creek Bridge. Work includes:

  • Widening and paving shoulders a minimum of 8’ in each direction
  • Providing a continuous 14’ two-way left-turn lane (TWLTL)
  • Providing a 20’ Clear Recovery Zone (CRZ)*
  • Provide continuous passing lanes
  • Providing a 6’ unpaved shoulder in addition to the paved shoulder for slow moving agriculture equipment
  • Increasing paved shoulder width to 14’ at school bus stops to provide a safe area for loading and unloading school children
  • Installing rumble strips on the shoulders and both sides of TWLTL or centerline
  • Straightening horizontal curves (to improve sight distance)
  • Flattening vertical curves (to improve sight distance)
  • Widening and paving local road intersections to accommodate truck turning movements
  • Reconstructing driveways
  • Replacing or extending culverts as needed
  • Placing asphalt concrete overlay
  • Relocating utility poles

* The CRZ begins at the edge of the travel lane. The CRZ includes the paved and unpaved shoulder for 20’ and will be cleared of fixed objects such as utility poles, trees and ditches.

Project Need

This segment of State Route 70 has had 85 reported collisions from August 2010 and August 2013. These collisions  include 7 fatalities and 32 reported injury accidents with 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.

Project Cost

The total project cost is estimated at $131 million in federal and state funds.
