March 11, 2021 - As the local agency responsible for maintaining the Call Box Program in Mendocino County, the Mendocino Service Authority for Freeway Emergencies (SAFE), is currently working to facilitate a necessary, system-wide upgrade.

The majority of call boxes in Mendocino County operate on cellular service, and the service provider has recently transitioned from 3G to 4G network technology. Unfortunately, the internal radios of the call boxes were designed to work with the former 3G service. As a result, many boxes have become inoperable until their hardware can be upgraded for compatibility with the newer cellular signal.

Staff is working closely with the provider and technicians to upgrade the radios. However progress has been delayed by the limited availability of the new radios and statewide demand.  While working through this upgrade process, staff continues to monitor and place call boxes in out-of-service status until they begin operating correctly.

Mendocino SAFE appreciates the patience of all travelers during this transition and upgrade. To report a call box not working properly, please call (707) 463-1859.
