US 180 Winter Traffic Study
Flagstaff enjoys a tourism boost after abundant snowfalls. The snow attracts visitors eager to ski, sled, and play outdoors. Unfortunately, the visitors that Flagstaff attracts also cause extreme winter traffic congestion along the U.S. 180, the primary route to the ski and snow play areas.
In response to the frustration felt by the local community including neighborhood groups, emergency responders, and area businesses, the Flagstaff Metropolitan Planning Organization (FMPO) is undertaking a study to identify and evaluate solutions to Flagstaff's winter congestion challenges. The study has recommended implementable immediate, mid-term, and long-term alternatives to ease the peak weekend winter traffic congestion.
Current Updates & Progress
Completed in 2012, this effort identifying solutions for heavy winter traffic is being updated with efforts by the Arizona Department of Transportation (ADOT) and Northern Arizona Intergovernmental Public Transportation Authority (NAIPTA) in 2018. FMPO is a participant in both of these efforts.
ADOT is examining permanent alternatives within the existing corridor and on alternate routes. NAIPTA is evaluating how transit can address peak winter traffic congestion and if a temporary egress route could help relieve pressure on the corridor.
