State Route 70 Safety Improvement and Passing Lanes Project – Yuba County
Latest Construction News
YUBA COUNTY (October 28, 2022) DeSilva Gates Construction is scheduled to work during the night-time hours on Monday, October 31, to shift traffic to the newly paved section of roadway between Laurellen Road and Woodruff Lane.
Motorists also should be watch out for flaggers handling intermittent traffic control as crews work on the transition to the new roadway section. The traffic shift will allow the contractor to work on the other side of the newly paved segment.
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. The construction zone speed limit has been reduced to 45 mph.
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.

- 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

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.
