Bane Canyon Access Road

Share on:

In San Bernardino County near the borders of Los Angeles, Orange, and Riverside Counties, the City of Chino hills houses the Chino Hills State Park. This park includes amenities such as hiking, biking, horseback riding (including on-site stables), car and tent camping, and site seeing.

The entrance to the park was a treacherous, narrow dirt road, within Bane Canyon. About two and a half miles into the park grounds, an existing paved two-lane road provided access to amenities. Rain events forced the park to close for several days afterwards due to the dangers associated with the dirt road.

State Parks planned to improve the first two and a half miles of the dirt road up to the location where the existing paved road begins, making it safer to enter the park and encouraging tour groups, school field trips, and citizen participation in the activities available at the park. The road runs through a major flood plain and over steep terrain with many surficial and deep landslides. The project includes two bridges, four large culverts, several thousand feet of soil nail retaining walls, new roadway, maintenance building and comfort station, entrance kiosk, septic systems, water line connections, electrical connections, telephone connections, and walking/horse trails.

Project highlights:

  • Two miles of entrance roads
  • Two miles of underground utilities
  • Entrance station, office and restroom construction
  • Comfort station
  • Trailhead
  • Scenic overlook
  • Stormwater pollution prevention
  • Maintenance facility
  • Intersection modifications
