Description	The Interstate 17 improvement project involved construction along a 23-mile corridor from Anthem Way to Sunset Point in Arizona. The project included widening 15 miles of roadway between Anthem Way and Coldwater Road in Black Canyon City, replacing two bridges, widening 10 others, and adding eight miles of flex lanes between Black Canyon City and Sunset Point. The flex lanes operate as an additional two-lane roadway that carries one direction of traffic at a time, alternating between northbound and southbound traffic depending on demand. The project was completed in December 2025 after starting in 2022, with finishing touches like survey work and landscaping ongoing.
