Good news for the Priest River area! Core Fiber is bringing high-speed fiber internet to more homes and businesses throughout the region, with new service available south of the Pend Oreille River and additional expansions underway near Oldtown, Idaho, and Newport, Washington.
Our growing network includes recently completed coverage along Old Priest River Road, with more construction underway on both sides of the Pend Oreille River near Oldtown and Albeni Falls. Together, these projects encompass approximately 1,180 potential serviceable addresses, building on the network and local relationships established by MiFiber, which is now part of Core Fiber.
