Ridge Route Preservation Organization

In 1909, California was on the cutting edge of the Good Roads movement. $18 million of state bonds were passed to construct the revolutionary new highway system. Stagecoach roads would soon be a thing of the past and the automobile would take center stage. 

When they set out to build the Ridge Route, they were entering uncharted territory. Built by a railroad contractor who believed in the future of the automobile, paved later by WW1 veterans with experimental road surfaces and designed with the purpose of uniting a rapidly splitting California. This road changed the course of history and eventually, its successor, the I-5, would become one of the most important trade routes in the country. 

We say this to inform you that the Ridge Route isn’t just another winding road. It has been a core part of our community since its opening in 1915 and a key part of our local history. Something worth honoring and protecting. While we understand that progress is inevitable, our organization exists to preserve what we can and document and recover what we can’t. 

The proposed expansion of the Northlake Development will impact the Ridge Route, realigning 1.5 miles of the road and developing alongside nearly 4 miles of this historic corridor. Along the western border of the project site, hidden off to the edges of the road are C Blocks. Concrete markers placed by the California Highway Commission during the surveying and construction of the road (1913-1915) to mark the original right-of-way. The project site also covers the historic locations of “Queen Nell’s Castle” – the homestead of Cornelia “Nellie” Martinez Callahan, and the Owl Garage. Both locations are no longer standing but could have artifacts such as bottles, plates and old car parts. Our organization would like to work with your archaeologists to ensure these markers and artifacts are collected and protected. 

Of concern for the future, we worry about the impact of relying on one road to be the only exit for an entire community. The Ridge Route is no stranger to fires and the area was referred to as a “historic fire corridor” in the Northlake Environmental Impact Report. Fires reported at Templin Highway and the I-5 are ever prevalent. The project site burned in the 2022 Route Fire and was under evacuation as recently as the 2025 Hughes Fire. With the widening of the road to 4 lanes, there would now be two southbound lanes and one northbound lane available for evacuation and potentially only for 30 minutes in the case of the “Freeway Spot Scenario” (Northlake EIR). 

It is out of concern for the future residents that we suggest looking into creating a secondary southern exit route for the community. Not only for evacuations, but to alleviate traffic on Ridge Route Road, which often functions as a bypass for the I-5 when there is an accident north of Castaic. Allowing residents to come and go unaffected by the freeway conditions. 

The Ridge Route Preservation Organization hopes to work with your archaeologist to preserve and honor our local history and encourage your developer to take measures to ensure the safety of future residents. Thank you for your time and consideration.
