Interstate 17 Junction State Route 179 to Interstate 40

The Arizona Department of Transportation and the Federal Highway Administration are conducting engineering and environmental studies to develop a long-range plan for the improvement of the I-17 corridor between the SR 179 traffic interchange (TI) in Sedona and the I-40 TI in Flagstaff. A series of improvements will be developed to provide for greater capacity and to ensure smooth operations for the traffic volumes that are projected to occur over the next 20 to 30 years. The design concept report will consider roadway, bridge and drainage improvements. Environmental issues will also be assessed. When the reports are complete, potential projects will be identified and priorities established for future inclusion in ADOT's construction program when funding is available.
