ADOT is constructing improvements to the storm water drainage system along I-17 between Greenway Road and Dunlap Avenue to reduce the potential for flooding at the cross streets. The improvements include constructing a new storm drain system to direct storm water into the Arizona Canal Diversion Channel, new drainage basins at Thunderbird Road, and removing the existing pump stations at the cross streets.
