Crews will continue work over the next two weekends to improve the ride on six miles of Interstate 17 between Happy Valley Road and State Route 74.

Here, according to the Arizona Department of Transportation, are upcoming weekend restrictions:

• Southbound I-17 will be closed at Loop 303 from 10 p.m. Friday, Sept. 13, to 5 a.m. Monday, Sept. 16. Traffic will detour along the off- and on-ramps at Loop 303. Southbound I-17 also will be narrowed to one lane between Loop 303 and Jomax Road.
• Northbound I-17 will be narrowed to one lane between Loop 303 and SR 74/Carefree Highway from 9 p.m. Friday, Sept. 20, to 5 a.m. Monday, Sept. 23.

“Lengthy traffic backups are unavoidable during freeway closures like those required along I-17, so drivers should plan ahead,” state transportation officials stated in a release.

The I-17 pavement work between Happy Valley Road and SR 74 is separate from the I-17 improvement project underway north of Anthem Way. For more information about that larger project visit improvingi17.com.
