LEWISTON, ID – The Port of Lewiston has broken ground on a major infrastructure project designed to expand broadband access across North Central Idaho. The 92-mile “middle mile” fiber optic backbone will form the state’s first north-south fiber network, with the goal of bringing reliable, affordable, and accessible high-speed internet to underserved rural communities.

The project’s first phase, now underway, involves construction of fiber from Moscow to Lewiston. A second phase will extend the line south to Grangeville. The initiative is funded through a combination of U.S. Department of Commerce Economic Development Administration funds, an Idaho Broadband Advisory Board grant, and local Port dollars. Crown Utilities, an Idaho-based company, is leading the construction.

Port of Lewiston General Manager Scott Corbitt said the effort is a key step toward bridging the state’s digital divide. “This middle mile backbone will help create the first north-south fiberoptic network within the state of Idaho. Not only will the benefits of enhanced connectivity and accelerated economic development flow to the residents of North Central Idaho, but the entire state will finally feel the effects,” Corbitt said.

The Port’s contribution will also link to a broader regional network through a collaboration with the Idaho Regional Optical Network and the Intermountain Infrastructure Group, extending connectivity from Grangeville to Star, Idaho. Port Operations Manager Jen Blood emphasized the long-term value of the project, noting it will provide a “redundant and resilient fiber optic pathway” and open opportunities for expanded service in rural areas.

The Middle Mile project is expected to be completed in spring 2027. In combination with other Port-sponsored fiber initiatives, officials say the work will position North Central Idaho as one of the most comprehensively connected regions in the state.
