Attention drivers and night owls in Flagstaff: gear up for a slight detour if your evening plans include passing through the intersection of Riordan Dr. and Riordan Ranch St. The city has announced an upcoming closure of this intersection, but with a silver lining—there won't be any daytime disruptions to reroute your commute. From tomorrow to Thursday, the roads will be shut down for traffic from 7 p.m. to 6 a.m. as crews work tirelessly through the witching hours to install crucial updates to the water system and underground utilities.

The updated schedule is a change of plans from the previously set dates that were to begin next Monday, and unlike the initial announcement, this time around, the daytime hours from 6 a.m. to 7 p.m. will remain open for traffic which allows local businesses to breathe a sigh of relief as their operations can continue unimpeded during peak hours. According to a release from the City of Flagstaff, "Access to businesses in the area will be maintained throughout the project."

The necessity for this infrastructure upgrade stems from the installation of a new water meter that's part of the city's efforts to improve its utility services for residents and business owners alike. Precision and efficiency seem to be the driving forces behind the rescheduling, and the city expresses gratitude for the public's patience and understanding in the face of these temporary inconveniences.

If you have any queries or concerns about how this might affect you, City of Flagstaff Senior Project Manager Ivey Coss is the point of contact; questions can be directed to Ivey via email at [email protected] or a quick call to 928-863-4980 could clear any confusion during this time, the city prides itself on open lines of communication and urges residents to reach out with any questions or concerns they might have. The City of Flagstaff's announcement emphasizes, "The City of Flagstaff appreciates your cooperation and understanding as we work to improve the City’s infrastructure."
