Southbound I-17 Slope Repair Starts March 15

Expect half-hour delays at night near Sunset Point


Drivers who use southbound Interstate 17 to travel from northern Arizona into the Phoenix area at night should plan on delays of approximately 30 minutes starting next week.

The Arizona Department of Transportation will begin overnight repair work Monday night (March 15) on a slope next to southbound I-17 about two miles south of the Sunset Point Rest Area.

For safety’s sake, ADOT has been monitoring the slope for a couple of weeks because a portion of it, saturated by recent rains, shifted and exposed loose rocks.

Southbound I-17 will be narrowed to one lane south of Sunset Point from 7 p.m. to 7 a.m. Monday through Thursday nights over a two-week period.

Drivers are asked to slow down, allow extra travel time, and follow directional signs while staying alert for workers and equipment in the area.

Information about highway conditions across Arizona is available by visiting ADOT’s Travel Information site at or by calling 5-1-1.

As part of ADOT’s public safety mission, crews will concentrate their overnight work on removing loose rocks along the I-17 slope to reduce the risk of rock fall in the area.
