WILLIAMS — Northern Arizona drivers who use Interstate 40 are advised to plan for travel delays as crews return to complete paving, bridge and intersection work between Parks and Williams.

The following I-40 ramp closures and detours are scheduled while crews reconstruct the on- and off- ramps at Grand Canyon Boulevard:

• Monday, May 13, from 6 a.m. to noon, crews will close the eastbound on-ramp at Grand Canyon Boulevard to complete guardrail work. DETOUR: Grand Canyon Boulevard traffic accessing eastbound I-40 traffic will head westbound on I-40 to exit at Country Club Road (exit 161) and enter eastbound I-40.
• Thursday, May 16, through Wednesday, May 22, from 6 a.m. to 6 p.m., crews will close the westbound I-40 off-ramp at Grand Canyon Boulevard. DETOUR: Westbound I-40 traffic accessing Williams will exit at Country Club Boulevard (exit 161) and enter eastbound I-40 to exit at Grand Canyon Boulevard.
• Tuesday, May 28, through Tuesday, June 4, from 6 a.m. to 6 p.m., crews will close the westbound I-40 on-ramp at Grand Canyon Boulevard. DETOUR: Southbound Grand Canyon Boulevard traffic will use westbound historic Route 66 and enter westbound I-40 at Country Club Boulevard (exit 161).

The eastbound and westbound I-40 ramps at Grand Canyon Boulevard will NOT be closed at the same time or over Memorial Day weekend.

In early summer, crews will put down new asphalt on 17 miles of I-40 in both directions between Parks and Williams. The project also includes a final layer of asphalt, known as friction course, to further improve the roadway surface, as well as installation of guardrail, striping and signage. The project is scheduled for completion in late 2019.

Motorists should allow extra travel time and plan for possible delays while work is underway.
