CHINO VALLEY, Ariz. (AP) -- The Arizona Department of Transportation says repair work is starting on Hell Canyon Bridge on State Route 89 north of Chino Valley and that motorists should be prepared for delays.
The state made temporary repairs to the bridge's damaged surface back in January but has hired a contractor to make more permanent repairs.
According to ADOT, the work involves removing and replacing deteriorating concrete from the deck, installing support beams, replacing other structural pieces and sealing the entire deck.
ADOT says SR 89 will be narrowed to one lane for seven days a week, 24 hours a day until the project is complete.
"A temporary signal will be in place at both ends of the bridge and the speed limit will be reduced to 25 mph to allow drivers to safely travel through the work zone," the ADOT website warns. "Drivers can expect possible delays of up to 30 minutes. Drivers should use extreme caution when workers are present on the bridge."
Repairs should be finished before the end of the month.
