Mitigating impacts to day-trippers, commuters and truck drivers will challenge a Kiewit-Fann joint venture when it begins construction in 2022 on the high-volume 23-mile stretch of I-17 from Anthem Way to Sunset Point less than an hour north of Phoenix.
Improvements on the $445.94-million project include new northbound and southbound general purpose lanes on 15 miles of the freeway from Anthem Way to Black Canyon City. The scope also calls for replacing two bridges and a bridge deck, widening six bridges and adding an eight-mile flex lane system. The Arizona Dept. of Transportation project, including construction and administration, will take three years to complete.
