Watch for work zones, plan for delays

As work continues on Interstate 17 south of Flagstaff for fiber-optic cable installation, motorists should plan for lane closures in the week ahead. The Arizona Department of Transportation urges motorists to slow down, be prepared to merge into the open lane and use caution around construction personnel and equipment while the following lane closures are in place:

Northbound I-17

• Northbound I-17 will be narrowed to one lane nightly (right lane closed) from Anthem Way to the Sunset Point Rest Area (mileposts 229-252) from 7 p.m. to 6 a.m. beginning Sunday evening, June 12, to Friday morning, June 17.

       -  A vehicle-width limit of 14 feet will be in place.

• Northbound I-17 will be narrowed to one lane (right lane closed) from north of State Route 169 to General Crook Trail (mileposts 281-285) daily from 5 a.m. to 5 p.m. beginning the morning of Monday, June 13, through the evening of Thursday, June 16.

      -  A vehicle-width limit of 16 feet will be in place.
