Plan ahead to avoid westbound I-10 weekend closure west of downtown Phoenix
Motorists traveling to the West Valley this weekend should allow extra travel time and plan ahead to avoid a closure of westbound Interstate 10 (Papago Freeway) at 51st Avenue due to construction of the Loop 202 South Mountain Freeway, according to the Arizona Department of Transportation.
Beginning 10 p.m. Friday, April 20, westbound I-10 between 51st and 59th avenues will be closed until 5 a.m. Monday, April 23. The closure will ensure a 100-foot crane can safely remove temporary structures used to support a concrete structure, also known as a straddle bent, for a future flyover bridge that will connect to the South Mountain Freeway.
During the closure, westbound I-10 traffic will be able to exit the freeway at 51st Avenue. Westbound traffic will be detoured to McDowell Road and can return to westbound I-10 at 59th Avenue. The westbound I-10 on-ramps at 35th and 43rd avenues will also be closed as well to help reduce backups.
A second weekend closure (May 4-7) will be needed for additional bridge construction.
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.
