HM4-TMS Eureka 25/26 (01-0P790)

Caltrans District 1 - Eureka is implementing a state-funded project, identified as HM4-TMS Eureka 25/26 (01-0P790), to modernize aging Traffic Management Systems (TMS) infrastructure in Humboldt County. The scope of work focuses on the replacement of obsolete assets that have reached the end of their lifecycle, specifically targeting Route 101 between postmile 78.4 and 79.4. Key deliverables include the installation and upgrade of Closed-Circuit Television (CCTV) units, traffic signal heads, interconnecting wiring, and cabinet components. Additionally, the project involves repairing electronic components and switches within Changeable Message Sign (CMS) boards, as well as replacing inductive loop detectors, traffic count devices, and associated communication hardware. All project activities are confined to the existing State right of way, with equipment staging limited to paved surfaces and non-vegetated turnouts to ensure no tree removal or soil and vegetation disturbance occurs outside pavement limits. The project is classified as a Class 1 Categorical Exemption under California Code of Regulations title 14, section 15304, as it consists of minor alterations to existing facilities with no significant environmental impact. While the project is currently listed as a forecast with a posted date of July 29, 2025, and is managed by Coady Reynolds, specific contract values, performance periods, and formal evaluation criteria have not yet been disclosed. Final inspection and acceptance will be conducted on-site by Caltrans.
