Closure Needed To Apply Rubberized Asphalt For South Mountain Freeway Project

By Arizona Department Of Transportation

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) between 51st and 83rd avenues. The closure will allow crews to apply a new layer of rubberized asphalt through the Loop 202 South Mountain Freeway work zone.

Westbound I-10 will be closed between 51st and 83rd avenues from 10 p.m., Friday, May 10, to 5 a.m., Monday, May 13.

With heavy traffic and delays expected, drivers should consider alternate routes such as 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 on-ramps at 27th, 35th and 43rd avenues will be closed to help prevent backups.

The entire length of the I-10 work zone, 4.5 miles between 43rd and 75th avenues, is getting a new riding surface. Work began last weekend at 63rd Avenue, and crews will complete work east of 63rd Avenue to 43rd Avenue in the fall after bridge work is complete in the I-10 median.

During the closure, crews will mill off the top inch of pavement that has reached the end of its service life and replace it with a new top layer of rubberized asphalt.

The 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.
