Project Benefits

This project will improve safety along State Route 70 corridor by providing continuous passing opportunities for vehicles from Ophir Road to Palermo Road. 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.
