Motorists traveling next week between Phoenix and Flagstaff need to plan ahead, be alert for work zones and allow extra travel time due to a pavement improvement project that is entering its final stages along Interstate 17, midway between Cordes Junction and Camp Verde.

Work hours have primarily been overnight, but starting on Tuesday, Sept. 16, crews will begin applying the new top layer of rubberized asphalt, which is temperature sensitive and needs to be completed during daytime hours.

Drivers can expect I-17 to be narrowed to one lane in each direction between the Dugas Road/Orme Road exit and the State Route 169 junction (mileposts 269-279) from 5 a.m. to 5 p.m. during weekdays (Monday through Thursday) through the end of this month.

In addition, the I-17 on- and off-ramps at the SR 169 interchange will be closed intermittently beginning at 5 p.m. on Sunday, Sept. 14 through 10 a.m. Monday, Sept. 15. Delays of up to 30 minutes are possible.

The work zone will be clearly marked by temporary barricades and signage. ADOT advises drivers to allow additional time to reach their destinations and to proceed through the work zone with caution, comply with the reduced speed limit, and be alert for construction equipment and personnel.
