Middle-Mile Broadband Initiative

In July 2021, Governor Gavin Newsom signed into law Senate Bill 156 to create an open-access middle-mile network to bring equitable high-speed broadband service to all Californians. SB 156 provides $3.25 billion to build the necessary infrastructure to bring internet connectivity to homes, businesses and community institutions. The design and construction of the middle-mile network is monitored by the Middle-Mile Advisory Committee (MMAC).

California’s Digital Divide

Millions of Californians lack access to high-speed, reliable internet. Some don’t have internet speeds fast enough for their needs, and some have no connection at all. As we have recently experienced, and which has been amplified by the COVID-19 pandemic, it is absolutely essential to have reliable internet to be able to work, attend school, access healthcare services, and connect with family and friends. California is building an open-access middle-mile network so service providers can reach unserved or underserved Californians.

Broadband For All

California is strengthening broadband connections to improve access to education, health services and employment opportunities throughout the state. The Middle-Mile Broadband Initiative is the first step to creating an open-access, middle-mile network that will build infrastructure to bring high-speed broadband service to unserved and underserved communities, regardless of technology used, on equal economic and service terms.

What is the Middle-Mile Broadband Network?

The middle-mile is the physical fiber optic infrastructure needed to enable internet connectivity. It is made up of high-capacity fiber lines that carry large amounts of data at high speeds over long distances. An open-access network gives providers and entities access to broadband infrastructure that will allow any networks to connect on equal economic and service terms.

Implementation

CDT has developed the Statewide Middle-Mile Network Map that displays where routes are planned and in development. The MMBI team continues its work to close the digital divide through an innovative approach that includes broadband construction, leasing, and joint build. 

In addition to construction, CDT continues to work with industry on exploring additional delivery methods.  A second Request for Innovative Ideas (RFI2) procurement was released in the Fall of 2023. RFI2 proposals are currently being evaluated.
