Overnight Closures, Traffic Restrictions for I-10 Construction in Phoenix

The Arizona Department of Transportation reports that late-night motorists traveling on westbound Interstate 10 (Papago Freeway) at 59th Avenue should prepare for overnight closures early next week and lane restrictions the remainder of the month as crews work on the flyover bridge structures that will eventually connect to the Loop 202 South Mountain Freeway.

Motorists using westbound I-10 toward the West Valley are encouraged to adjust their travel schedules to avoid the closures and lane restrictions, or allow extra travel time due to heavy traffic, according to the Arizona Department of Transportation.

The following I-10 overnight closures and traffic restrictions at 59th Avenue are scheduled during July:

  • Westbound I-10 closed at 59th Avenue from 9 p.m. Monday (July 10) to 5 a.m. Tuesday (July 11), from 9 p.m. Tuesday to 5 a.m. Wednesday (July 12) and from 9 p.m. Wednesday to 5 a.m. Thursday (July 13).
  • Westbound I-10 narrowed to one lane with brief intermittent closures at 59th Avenue from 9 p.m. Thursday to 5 a.m. Friday (July 14) and from 10 p.m. Friday to 5 a.m. Saturday (July 15).
  • Westbound I-10 narrowed to one lane overnight with brief intermittent closures at 59th Avenue from 9 p.m. to 5 a.m. Sunday through Thursday nights (July 16-20) – ending at 5 a.m. Friday.
  • Westbound I-10 narrowed to one lane overnight with brief intermittent closures at 59th Avenue from 9 p.m. to 5 a.m. Sunday through Thursday nights (July 23-27) – ending at 5 a.m. Friday.

During freeway closures, westbound I-10 traffic will detour along the off- and on-ramps at 59th Avenue.

The scheduled restrictions are subject to change due to inclement weather or other unforeseen factors. The project team will update the schedule of planned restrictions if necessary.

The 22-mile South Mountain Freeway, expected to open by late 2019, will provide a long-planned direct link between the East Valley and West Valley and a much-needed alternative to I-10 through downtown Phoenix. Approved by Maricopa County voters in 1985 and again in 2004 as part of a comprehensive regional transportation plan, the South Mountain Freeway will complete the Loop 202 and Loop 101 freeway system in the Valley.
