The first phase of work for the Arizona Department of Transportation’s long-awaited Interstate 17 Improvement Project from Anthem Way to Sunset Point is now underway. The $446 million project, which will add capacity and reduce congestion along this heavily traveled corridor, is expected to take approximately three years to complete. It includes 15 miles of widening from Anthem Way to Black Canyon City and the construction of approximately eight miles of flex lanes from Black Canyon City to Sunset Point. Drivers can expect various construction activities through the 23-mile corridor and should plan their trips accordingly.
