Northbound Interstate 17 will be narrowed to one lane between Loop 303 and State Route 74 in north Phoenix from 9 p.m. Friday to 5 a.m. Monday for ongoing pavement improvement work.

The northbound I-17 off- and on-ramps at Dove Valley Road also will be closed this weekend, Sept. 20-23, according to the Arizona Department of Transportation.

Drivers can access Dove Valley Road by exiting at Loop 303 and continuing north on the frontage road. The northbound I-17 circular ramp to westbound SR 74 will be closed during nighttime hours, state transportation officials said.

Drivers should consider traveling during non-peak morning or nighttime hours and avoid using local streets east of I-17 as alternate routes. Those roads, ADOT officials said, are not designed for heavier freeway traffic.
