One lane for northbound traffic on I-17 will be temporarily closed with reduced travel speeds for a three mile segment just north of the SR 179 junction beginning Monday, Oct. 13. The lane reduction is required to allow for removal and installation of new pavement markers which provide greater visibility during weather events and are more durable under heavy traffic.

The marking replacement operation will continue weekly Monday through Thursday from 6 a.m. to 6 p.m., and is expected to be completed mid-November. During construction, drivers are asked to allow for extra travel time, exercise caution and observe reduced speeds within the construction zone.
