Interstate 17 lane restrictions scheduled in north Phoenix during overnight hours Sept. 15-18

Southbound I-17 exit at Pinnacle Peak Road set to close for several weeks

Drivers in north Phoenix should plan for overnight lane restrictions on Interstate 17 as construction of new interchanges continues at Happy Valley and Pinnacle Peak roads. The Arizona Department of Transportation advises motorists to slow down and use caution around construction personnel and equipment while the following restrictions are in place:

  • 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.
  • NOTE: An 11-foot vehicle-width restriction is in place on north- and southbound I-17 between Pinnacle Peak and Happy Valley roads.

COMING SOON:  The southbound I-17 off-ramp at Pinnacle Peak Road will be closed continuously from late September through mid-November. Crews are scheduled to construct the new southbound I-17 exit ramp. Detours: Drivers will be able to access Pinnacle Peak road in several ways. ADOT recommends allowing extra travel time and planning for possible delays. 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.

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.
