FLAGSTAFF, Ariz – The Arizona Department of Transportation, City of Flagstaff, and Fann Contracting are set to begin a project to construct a new roundabout that will replace the signalized intersection at Fourth Street and Cedar Avenue/Lockett Road to improve the safety and function of the intersection. This new roundabout will be designed with flashing pedestrian crossing beacons and will slow speeds,
help avoid angle collisions and add a crosswalk at the fourth leg of the intersection. Additional work includes the installation of water, sewer and storm drain infrastructure.
Preliminary construction activities are set to begin March 31, 2025. This work consists of tree removal, fence installation, concrete removal and storm drain installation along the perimeter of the intersection. Work may occur Monday through Friday, from 6 a.m. to 6 p.m., with occasional night work and weekend work as needed. During preliminary construction activities, the intersection of Fourth Street and Cedar Avenue/Lockett Road will remain open to motorists, bicyclists and pedestrians, however, expect lane and sidewalk restrictions, modified bus routes, heavy equipment, loud noise and flagging operations. Access for schools, businesses, and residents will always be provided. Please follow the marked signage and travel safely. Note that this work is highly weather dependent.
A full closure of the Fourth Street and Cedar Avenue/Lockett Road intersection is scheduled for the entire 2025 school summer break (May 23 to Aug. 4), with the full project anticipated to be complete in Fall 2025. The new roundabout will be installed during this full closure. Notifications will be provided prior to the full intersection closure with more information and associated detour routes.
