The Arizona Department of Transportation is planning to construct improvements to the drainage system along the Interstate 17 frontage roads between approximately Greenway Road and the Arizona Canal Diversion Channel (ACDC) just south of Peoria Avenue in Phoenix. The improvements will include a new gravitational flow drainage system utilizing various sizes of concrete pipes and the removal of the pump stations from the traffic intersections at Greenway, Thunderbird and Cactus roads and Peoria Avenue.
The purpose of the project is to improve drainage facilities that remove water from the crossroads at Greenway, Thunderbird and Cactus roads and Peoria Avenue and therefore reduce the potential for flooding. The proposed drainage improvements would discharge water to the Arizona Canal Diversion Channel (ACDC).

Construction is scheduled to begin in the Spring 2019.
