I-17 Frontage Road Drainage Improvement: Greenway Road to ACDC Canal

I-17 Frontage Road Drainage Improvement: Greenway Road to ACDC Canal

Contents

Overview

The Arizona Department of Transportation is constructing improvements to the cross street drainage system along the Interstate 17 frontage road between Greenway Road and Dunlap Avenue in Phoenix. The purpose of the project is to improve the drainage facilities that remove storm runoff from the Greenway, Thunderbird, Cactus, and Peoria cross streets, helping to reduce the potential for flooding at the Interstate 17 overpasses.

The improvements will include a new, gravity-powered storm drain system, utilizing various sizes of concrete pipes and new drainage basins at Thunderbird Road, and the removal of the existing pump stations from the cross streets.The new system will discharge stormwater into the Arizona Canal Diversion Channel (ACDC), north of Dunlap Avenue.

Project Schedule

Construction started in early 2020 and is anticipated to end mid 2023. Work began at the south end of the project near the Arizona Canal Diversion Channel and will proceed north to Greenway Road. Four phases of construction are scheduled:

  • ADOT will maintain access to homes, businesses and other properties in the project area via alternate routes.
  • Weekend, weekday and overnight work will be scheduled.
