Highway 89 Construction and Delays – Middle-Mile Broadband Network Project Summary
The State of California is currently constructing the Middle-Mile Broadband Network (MMBN) along State Route 89, stretching from Interstate 80 in Nevada County to the Sierra/Plumas County line. This project, managed by the California Department of Technology and overseen by Caltrans, is part of a statewide effort to expand access to affordable, high-speed internet, particularly in underserved and rural communities.
Construction work, being carried out by Teichert, includes the installation of:
* Broadband conduit and fiber optic cables
* Cable marker posts
* Underground vaults
This project supports the 2021 Senate Bill 156, signed by Governor Newsom, aimed at building an open-access middle-mile broadband network that will serve as the backbone for future local (“last-mile”) internet connections.
Expected Impact on Highway 89
Motorists should expect delays on Highway 89 throughout the summer as construction activities continue. Lane closures, reduced speed zones, and traffic control measures will be in place along various segments of the route during installation.
Residents, visitors, and commuters are encouraged to plan accordingly, allow extra travel time, and stay alert for construction crews and signage in the work zones.
The MMBN project is a critical investment in California’s digital infrastructure, supporting economic development, education, and emergency services across the state.
