Phoenix road closures: I-17 to become one-lane at these times

Southbound I-17 will be narrowed to one lane overnight only.

PUBLISHED OCT 3, 2024

Phoenix, Arizona: Work improving the Interstate 17 pavement surface in north Phoenix will occur overnight this weekend, with southbound I-17 reduced to one lane beginning on Friday, Saturday and Sunday nights.

Southbound I-17 will be narrowed to one lane overnight only between State Route 74/Carefree Highway and Dixileta Drive from 9pm Friday to 9am Saturday; 9pm Saturday to 9am Sunday; and 9pm Sunday to 5am Monday.

The Arizona Department of Transportation (ADoT) is continuing a much-needed project along I-17 between Happy Valley Road and State Route 74. An older and rough top layer of asphalt pavement has been removed and specialized equipment is now being used to diamond grind the base concrete pavement, creating a smoother, safer and longer lasting riding surface along 6 miles of I-17.

Drivers using I-17 southbound during these restrictions should budget extra time. They should avoid attempting to detour on neighborhood streets that aren’t designed for freeway traffic.

Future weekend restrictions

Beginning Friday night, October 11: Southbound I-17 narrowed to one lane starting at SR 74/Carefree Highway and closed at Loop 303/Sonoran Desert Drive, with traffic using off- and on-ramps.
