ADOT is installing high-speed fiber optic infrastructure along 67 miles of I-17 between the McGuireville Rest Area (north of Camp Verde) and Anthem Way. Work is expected to continue through mid-2022, and will proceed along I-17 in segments of several miles per week. Crews are installing conduit and pull-box systems, fiber optic cables, node buildings and load centers. Learn more on the project website or call the ADOT Project Information Line at 855.712.8530.
