PHOENIX — A project to reduce the potential for rockfall in a quarter-mile section of northbound Interstate 17 between Camp Verde and Flagstaff will require closures of up to 30 minutes overnight starting Sunday, April 17, according to the Arizona Department of Transportation.

Drivers using this route between 8 p.m. and 6 a.m. should plan ahead and budget extra time on the following dates, when intermittent closures will occur northbound near milepost 292 approaching McGuireville:

• Starting at 8 p.m. Sunday, April 17, and ending at 6 a.m. Friday, April 22.
• Starting at 8 p.m. Sunday, April 24, and ending at 6 a.m. Friday, April 29.

The project area is between Middle Verde Road (Exit 289) and the Rimrock/Lake Montezuma/Cornville exit at milepost 293.

Southbound I-17 traffic will be unaffected.

The project will remove rockfall debris and scale slopes to reduce the potential for rock to fall, among other work.

From April 17 through April 29, northbound oversize loads wider than 12 feet will be required to detour around the project area between 8 p.m. and 6 a.m. The detour for oversize loads is State Route 260 to Cottonwood, State Route 89A to Sedona and State Route 179 to I-17.

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