WILLIAMS – Northern Arizona drivers on Interstate 40 west of Flagstaff should plan for travel delays due to construction work between Parks and Williams. Crews have scheduled ramp closures and lane closures while a new layer of asphalt pavement is placed on 17 miles of east- and westbound I-40 between Parks and Williams this summer. The project also includes a final layer of asphalt, known as friction course, to further improve the roadway surface, and installation of guardrail, striping and signage. The project is scheduled for completion in late 2019.
