Weekend closure on westbound I-10 west of downtown Phoenix

Work continues on South Mountain Freeway interchange

PHOENIX – Westbound Interstate 10 will be closed at 35th Avenue this weekend to allow construction crews to work on signage related to the Loop 202 South Mountain Freeway interchange now under construction.

Westbound I-10 will be closed between 35th and 67th avenues from 10 p.m. Friday, Oct. 18, to 5 a.m. Monday, Oct. 21. In addition, ramps from Interstate 17 to westbound I-10 and westbound on-ramps at 27th, 35th and 43rd avenues will be closed during the work.

Drivers should expect long delays at 35th Avenue, the first westbound exit west of I-17. As an alternate, drivers should consider exiting I-10 no later than I-17, then driving north to McDowell Road or south to Van Buren Street and traveling west to re-enter I-10 at 67th Avenue, west of the closure.

Westbound I-10 drivers traveling beyond the Phoenix area should consider taking Interstate 8 west at Casa Grande and State Route 85 north from Gila Bend to re-enter I-10 in Buckeye. Drivers on southbound I-17 planning to drive west of Phoenix should consider Loop 101 or Loop 303 to connect with I-10.

The 22-mile South Mountain Freeway is scheduled to be open to traffic by the end of the year with construction activities continuing into 2020. 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.
