Southbound I-17 Exit at Pinnacle Peak to Close for Several Weeks
The southbound I-17 off-ramp at Pinnacle Peak Road will close in late September through mid-November as crews build now exit ramps as part of the new overpass under construction, ADOT announced. A specific date was not set. Alternate routes include:
- Exit southbound I-17 at Jomax or Happy Valley roads and travel east to southbound 19th Avenue; or
- Travel south on I-17 to the Deer Valley Road exit, then travel east to northbound 19th Avenue or west to northbound 35th Avenue.
Separately, some I-17 lane closures are planned for this weekend:
- Northbound I-17 will be narrowed to one lane between Pinnacle Peak and Happy Valley roads from 10 p.m. Sunday, Sept. 15, to 5 a.m. Monday, Sept. 16, and from 10 p.m. Monday to 5 a.m. Tuesday, Sept. 17.
- Southbound I-17 will be narrowed to two lanes at Pinnacle Peak Road from 10 p.m. Monday, Sept. 16, to 5 a.m. Tuesday, Sept. 17 and narrowed to one lane between Happy Valley and Pinnacle Peak roads from 10 p.m. Tuesday to 5 a.m. Wednesday, Sept. 18.
“Expect additional closures and restrictions on I-17, Pinnacle Peak and Happy Valley roads this fall as new off- and on-ramps are built, the existing Pinnacle Peak Road bridge is demolished, and traffic is switched onto the newly constructed westbound Pinnacle Peak Road bridge for the short-term,” the agency said in a statement.
