PHOENIX — Arizona Department of Transportation (ADOT) crews are performing nighttime operations on southbound Interstate 17 at the McGuireville exit (milepost 293), using new high tech injection technology to address needed repairs.

ADOT is injecting foam deep underneath the pavement as a way to smooth out dips on Arizona highways. This method is more cost efficient than ripping out old pavement, re-compacting the sub-grade, and placing new concrete or asphalt.

One lane of travel for southbound traffic will be closed in the construction zone from 7 p.m. to 7 a.m. nightly on Wednesday (July 20) through Friday (July 22). Work is also scheduled to occur at this location on Saturday (July 23) and Sunday (July 24) from 10 p.m. to 9 a.m.

ADOT advises travelers to observe reduced speeds in the area, watch for crews and equipment in the work zone and allow for extra time for travel. ADOT works to inform the public about planned roadway restrictions, but there is a possibility that unscheduled closures or restrictions may occur. Weather can also affect a project schedule.
