Motorists traveling from Flagstaff to Kingman should plan ahead, expect delays

Interstate 40 to close briefly in both directions Thursday morning for blasting operations near Parks
July 30, 2014

PHOENIX – Motorists traveling along Interstate 40 from Flagstaff to Kingman need to plan ahead and allow extra travel time as the Arizona Department of Transportation continues a rockfall containment project approximately 15 miles west of Flagstaff that will require weekly 30-minute rolling closures due to blasting operations.

Beginning at 9 a.m. on Thursday, July 31, a rolling closure for up to 30 minutes will be necessary in both directions of I-40 near Parks (mileposts 180-181) to allow crews to perform blasting rock cuts along the highway and clear debris from the roadway. In preparation for the blasting work, westbound I-40 is currently narrowed to one lane through the work zone until the restriction is lifted on Friday afternoon.

A weekly 30-minute rolling closure is scheduled to occur at 9 a.m. during mid-week until the project is completed. ADOT will notify the public in advance of the weekly rolling closures until the project is completed.

The $1.6 million safety improvement project is necessary to protect motorists and prevent damage to the highway from falling rocks, particularly during monsoon storms and heavy rains, while reducing the frequency of closures due to falling rocks. Work includes rock excavation and scaling, installing rockfall netting and constructing a wider rock ditch.

This is one of four current I-40 projects between Flagstaff and Kingman. ADOT recently started a $13.6 million project to upgrade a 15-mile segment between Rattlesnake Wash, five miles east of Kingman, and the US 93 junction (mileposts 57-72). The paving project is expected to be completed this fall.

ADOT is nearly complete with a resurfacing project from Ash Fork to Williams (mileposts 146-161). The $10.5 million project started last summer, and following a winter shutdown, the project will be completed this year. In the same vicinity, ADOT is also working on bridge rehabilitation projects from Ash Fork to West Ash Fork (mileposts 143-147).

ADOT works to inform the public about planned highway restrictions, but there is a possibility that unscheduled closures or restrictions may occur. Weather can also affect a project schedule.
