State Route 70 Corridor Improvements – Segment 2

Project Facts


  • Widen the existing 2-lane highway to five lanes.
  • Create a continuous two-way left turn.
  • Widen the shoulders to 8 feet.
  • Upgrade drainage systems.
  • Establish an area for vehicles veering off the roadway to return to the main highway.

Project Benefits

This project will improve safety along State Route 70 corridor by providing continuous passing opportunities for vehicles from Palermo Road to just north of Cox Lane. The corridor has experienced higher than average collision rates with the majority of accidents attributed to the lack of passing lanes. The additional lanes will increase highway capacity to meet future economic development, including population growth, in Butte County.
