Butler Avenue will be partially closed for about two months beginning Thursday between Cambridge Lane and River Run Road in Flagstaff. City of Flagstaff officials say the closure will limit Butler Avenue to one eastbound lane and one westbound lane. Detour routes for pedestrian and vehicle traffic will be posted around the partial closure. Officials say it’s necessary for utility and frontage improvements for the McGrath/Elara Multi-Family Project. If your daily commute takes you through the area, plan for extra time of find an alternate route.
