HM4-TMS Calpella CMS 26/27

Caltrans District 1 in Eureka is preparing to replace outdated Changeable Message Sign systems along with associated wiring, cabinets, controllers, and related components within existing conduits and right-of-way boundaries. The project targets assets that have reached end-of-life, operate on obsolete technology, or are in deteriorated condition, aiming to modernize the traffic management infrastructure using current industry-standard equipment to improve system reliability and operational efficiency. All work is confined strictly to existing state-owned land, ensuring minimal disruption and adherence to regulatory limits. The initiative is designed to enhance traffic communication and safety for the traveling public by upgrading critical signage technology to current specifications. The project, titled HM4-TMS Calpella CMS 26/27, has been posted as a forecast on July 30, 2026, with no solicitation number assigned yet. It falls under the jurisdiction of the California Department of Transportation, and all activities will occur within the state of California.
