I-10 restricted nightly for South Mountain Freeway work in West Valley

February 25, 2019

PHOENIX – Both directions of Interstate 10 will be narrowed to one lane overnight in west Phoenix this week for bridge work at the Loop 202 South Mountain Freeway interchange.

Drivers should allow extra travel time, use caution and consider alternate routes while I-10 is restricted, according to the Arizona Department of Transportation.

The restrictions are scheduled as follows:

  • Westbound I-10 narrowed to one lane overnight between 35th and 59th avenues from 9 p.m. Monday to 5 a.m. Tuesday (Feb. 26).
  • Eastbound I-10 narrowed to one lane overnight three consecutive nights between 75th and 59th avenues from 8 p.m. Tuesday through 4 a.m. Friday (March 1).

The 22-mile South Mountain Freeway is scheduled for full completion in 2020, although traffic is expected to be using the freeway earlier. It 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.
