ADoT is improving the pavement along I-17 between Happy Valley Road and State Route 74.

PUBLISHED SEP 26, 2024

Please be aware of these restrictions to avoid any delays.

Phoenix, Arizona: Drivers planning to use northbound Interstate 17 (I-17) in north Phoenix this weekend should plan for slow traffic and delays when the freeway is narrowed to one lane near Loop 303. The Northbound I-17 will be narrowed to one lane between Loop 303 and State Route 74 in north Phoenix from 9pm Friday to 5am Monday, September 27-30.

The Arizona Department of Transportation (ADoT) is continuing a project to improve the pavement 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 traveling on northbound I-17 this weekend should allow extra time, travel during non-peak morning or nighttime hours and, if possible, consider traveling before the closure starts Friday night.

Please keep these further restrictions and measures in mind:

Neighborhood streets along North Valley Parkway will be limited to local traffic only.\

Not allowing right turns from the northbound I-17 off-ramp to eastbound Jomax Road (to discourage neighborhood cut-through traffic and help with overall traffic flow in the area).

Law enforcement officers and ADOT personnel will be positioned at several locations to help manage traffic conditions, including near the Happy Valley Road intersections at Norterra Parkway and 19th Avenue east of I-17.

Dixileta Drive will be closed at 27th Avenue near the city of Phoenix’s solid waste transfer station to reduce cut-through traffic.
