A portion of water line in Scottsdale Road between Princess and Mayo boulevards is causing pressure and water service reliability issues in the area and must be replaced. The project will require traffic restrictions along southbound Scottsdale Road for approximately 90 days beginning in late July.
The water line north of Mayo and south of Princess is a 16-inch pipe. The section of water line between Princess and Mayo is 12-inch and must be upsized to eliminate the pressure issues and leak risk. To shorten the project timeline and minimize service disruptions to the multiple fire hydrants and customers on the existing line, the city will be installing a parallel line in the southbound lanes and making tie-ins to the existing main at Mayo and Princess.
This innovative approach will reduce traffic impacts and create redundancy for future water line maintenance.
Traffic Control and ADOT Coordination
Southbound Scottsdale Road will be reduced to one lane between Mayo and Princess boulevards for the duration of the project. Northbound traffic will remain largely uninterrupted with localized, temporary closures at Mayo and Princess when the tie-ins are completed.
Scottsdale is coordinating with ADOT to minimize traffic impacts during the ongoing construction project on Loop 101.
Drivers are encouraged to use alternate routes. (Suggested routes include Pima and Tatum roads.)
Work Hours and Project Timeline
Construction hours will be 6 a.m. to 4 p.m. Monday through Friday with occasional weekend work if necessary to remain on schedule.
Construction is scheduled to begin July 22 with expected completion in late October, prior to holiday and event seasons.
