Map Update Log
The purpose of the Statewide Middle-Mile Network Map is to visualize the network that will connect communities that are unserved and underserved by current broadband services.
As the network develops through specific funding levels, planning, lease, purchase, joint build, and Caltrans-led construction, any route refinements and updates that are one-half mile or more will be reflected on this log.
