Expanding broadband internet access for Arizonaโs underserved rural residents is the goal of a new state plan to build fiber-optic backbones along major interstates and highways.
The Arizona Commerce Authority, in partnership with the state Department of Transportation, last week unveiled the Arizona Statewide Broadband Middle-Mile Strategic Plan, with the creation of the Statewide Middle-Mile Network, which supports current broadband expansion efforts on Interstate 17 and Interstate 19 and future expansion on those and other interstate and state highways.
The Commerce Authority and its new state Broadband Office say Arizonaโs rural and tribal communities now lack accessibility to fast, affordable, and reliable broadband service.
The Commerce Authority cited data showing that most U.S. Census blocks in Arizona have a single service provider, and about 2.1 million out of 2.6 million Arizona households are connected to some form of internet.
But that leaves about 400,000 households with no internet access and an equal number with substandard service like dial-up, and internet speeds in non-metropolitan areas fall short of the stateโs goal for download speeds of 100 megabits per second and uploads of 20 Mbps, the state agency said.
The new plan targets so-called โmiddle mileโ infrastructure โ high-capacity fiber optic lines that carry data over long distances but donโt reach end users โ as a key obstacle to expanding broadband in less populous areas of Arizona.
The plan seeks to drive expansion of those middle-mile data pipes, while encouraging private companies to invest in infrastructure to connect broadband lines to consumers who are now underserved.
Some of that work is already underway.
ADOT is spearheading two active projects to install conduit to carry fiber-optic cables along I-19 and I-17, expecting to add 200 miles of conduit by early 2023. The highway agency plans to use broadband to provide โsmart highwayโ technology, such as overhead message boards and traffic cameras.
In November, Gov. Doug Ducey announced the state would use $100 million in federal funding from the American Rescue Plan Act to expand broadband in undeserved communities across the state.
In fiscal 2020, state lawmakers allocated $3 million for a Rural Broadband Development Grant program that has funded projects in Bullhead City, Page and Payson, while funding planning grants in other parts of the state.
