Public Notice: Cromberg Rehab & Feather River Inn Intersection Project

Cromberg Map

Project Description 

Caltrans District 2 is proposing to rehabilitate and widen an approximate 20-mile section of Highway 70 between the communities of Cromberg and Portola in Plumas County. The proposed work includes reconstructing the roadway and adding 4 to 8-foot paved shoulders where there is currently little or no paved shoulder. Additional improvements include minor curve realignments, raising the highway in Deleker to reduce the occurrence of highway flooding, replacing the bridge rail at Humbug Creek Bridge, road widening at the Feather River Inn Road intersection, repaving the park and ride at the intersection of Highway 89 and 70, and bringing drainage systems, guardrail, and signage up to current standards throughout the project limits. 

Improvements in the City of Portola will include updating curb ramps to Americans with Disabilities Act (ADA) standards, constructing a new sidewalk in one location that does not currently have a sidewalk, repaving, and potentially re-striping to reduce the number of through lanes from two in each direction to one in each direction in order to provide bike lanes and on-street parking throughout the city. A final decision on re-striping will be made following input on the proposal.
