ADOT warns of potential I-17 closure in No. Arizona

Posted: Updated:

PHOENIX (AP) -- Arizona Department of Transportation engineers are monitoring two slopes adjacent to southbound Interstate 17 between Sunset Point and Black Canyon City for potential rock slides.

Heavy rains over the past month have saturated the slopes and increased the potential of rocks falling onto the roadway.

ADOT crews and equipment are on site and engineers are assessing the slopes to determine the steps needed to maintain a safe roadway and vital route between Flagstaff and metro Phoenix.

Should conditions warrant, ADOT crews are in position to immediately close the southbound lanes.

A landslide could require closure of both southbound I-17 lanes and up to seven hours to clear. At this time, northbound I-17 is unaffected.

Drivers are urged to call 5-1-1 before traveling on I-17 southbound through the area to avoid unexpected delays or detours.
