Multiple road improvement initiatives commenced in early March, marking the onset of the 2026 construction season. The City of Flagstaff and Ames Construction initiated work on Lone Tree Road from O'Leary Street to Butler Avenue on March 2.[1]
The City of Flagstaff and Ames Construction will begin roadway improvements on Lone Tree Road and Butler Avenue starting March 2, 2026. The project is expected to be completed in December 2026. Thank you for your patience and cooperation as we work to improve the area.[1]
The scope encompasses roadway reconstruction, installation of water, sewer, and storm drain lines, sidewalk and driveway enhancements, and the addition of bike lanes and multi-use paths. Temporary lane restrictions and detours are in effect during weekday hours from 6 a.m. to 5 p.m., while maintaining local access for residents and businesses.[1] Mountain Line bus routes, including 3, 4, 7, and 14, implemented detours with temporary stops near Sawmill Road and other locations starting the same day.[5]
Road Repair Program Advances
A March 4 update on the Road Repair and Street Safety Program revealed ongoing design work for 2026 projects. City staff, in collaboration with engineering consultants, evaluated a draft list of streets using a pavement scoring system. Targeted locations include Woodlands Village Boulevard, Marketplace Drive, Switzer Canyon Drive, Columbus Avenue, Zuni Drive, and others such as Highway 89, Industrial Drive, and Lockett Road. Treatments involve pavement preservation, curb and gutter repairs, sidewalk inspections for ADA compliance, and vegetation management.[2]
Coconino County also began the Spring Valley Road Pavement Rehabilitation Project on March 2, spanning Lillie J. Ranch Road to Rustic Cabin Trail. Valued at over $1 million, the effort aims for completion by summer 2026.[3]
These developments precede further state-led enhancements, such as pavement preservation on SR 64 starting March 3 and variable speed limit signage on I-40 anticipated in spring. Motorists should anticipate ongoing disruptions through the year as projects progress toward safer, more resilient roadways.[4]
