The Arizona Department of Transportation is scheduled to begin a paving project next week along a nearly 20-mile section of north- and southbound I-17 north of Phoenix.

Expect delays while traffic is guided through alternating travel lanes and speed is reduced to 55 mph.

Paving is scheduled to occur between 6:30 a.m. and 6:30 p.m. Monday, October 30, and Tuesday, October 31, between milepost 259 (Crown King Road) and milepost 278 (just south of State Route 169).

Drivers should proceed with caution, slow down and watch for construction personnel and equipment.
