Timeline
The closure begins on Wednesday, September 23, 2026, at 8 p.m.
The road is scheduled to reopen on Thursday, September 24, 2026, at 4 a.m.
Seasonal Patterns
The scheduled signal repair follows standard safety protocols established by the Manual on Uniform Traffic Control Devices to maintain intersection visibility and control. These routine maintenance windows are typical for aging infrastructure requiring periodic updates to ensure continued reliability.
Motorists traveling through Flagstaff on Wednesday night should plan to use Fanning Drive to circumvent the closure. Drivers should expect minor delays and proceed with caution through the detoured route until the intersection reopens on Thursday morning.
