Westbound I-10 to close west of downtown Phoenix this weekend

Work continues on South Mountain Freeway interchange

South Mountain Freeway Project: Closure map for Westbound I-10 Weekend Closure between 51st and 67th avenuesPHOENIX – Motorists traveling toward the West Valley from downtown Phoenix this weekend should allow extra travel time and plan ahead to avoid a closure of westbound Interstate 10 (Papago Freeway) between 51st and 67th avenues due to construction of the Loop 202 South Mountain Freeway.

Westbound I-10 will be closed from 10 p.m. Friday, June 28, to 5 p.m. Sunday, June 30, in west Phoenix. The westbound I-10 on-ramps at 27th, 35th and 43rd avenues also will be closed to help reduce traffic backups.

Work will include replacing signs near the interchange of the South Mountain Freeway and I-10, installing a concrete barrier, adding a loop detection system as well as landscaping and irrigation.

To avoid delays on westbound I-10, motorists should consider alternate routes, including the Loop 101 (Agua Fria Freeway) west of Interstate 17, or exiting I-10 sooner and taking local streets to re-enter past the closure point.

Westbound I-10 traffic can exit at 43rd Avenue and detour either to the westbound I-10 access road or McDowell Road or Van Buren Street before re-entering the freeway at 67th Avenue. Drivers should expect heavy delays.

The 22-mile South Mountain Freeway is scheduled for full completion in 2020, although traffic is expected to begin 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.
