NORTH PHOENIX — Heavy rains this week have flooded underpasses along Interstate 17 in north Phoenix, but a fix begins in January.

Crews will install 90-inch pipes and new pumps to move water from Greenway, Thunderbird and Cactus roads into the Arizona Canal Diversion Channel.

“Finding parts and equipment is a challenge. Without question, the gravity-fed drainage system will be much better,” said John Bullen, MAG’s transportation, economic and finance program manager.

The area now has more traffic with aging infrastructure.

“It’s an opportunity to make a really important investment that people will be able to see immediately, to more efficiently drain that water from under those underpasses,” Bullen said.

The two-year construction project will cost $38.4 million. Voters approved the funding with Proposition 400 in 2004.

Wednesday, when rains were heaviest, cars were seen stuck outside of the flooded underpasses.
