Plan for Delays with Westbound I-10 Closed this Weekend in West Valley


I-10 Closure Statewide Notice 02 07 17

By Staff Reports

(Victor Valley) – Drivers planning to use Interstate 10 in the West Valley this weekend should allow extra travel time and consider alternate routes with the westbound lanes closed between 51st and 75th avenues to prepare for construction of a Loop 202 South Mountain Freeway interchange.

Expect heavy traffic and delays while the following closure is in place:

-Westbound I-10 closed between 51st and 75th avenues from 10 p.m. Friday, Feb. 10, to 5 a.m. Monday, Feb. 13. Westbound I-10 on-ramps at 35th and 43rd avenues will also be closed.

Westbound I-10 traffic will be rerouted along McDowell Road, just north of I-10. Drivers should expect traffic congestion on roads closest to I-10.

Valley motorists should consider other freeways, including the Loop 101 west of I-17. I-10 motorists not needing to travel through Phoenix should consider taking Interstate 8 and State Route 85 to connect back to westbound I-10.

Next weekend, eastbound I-10 (toward downtown Phoenix) will be closed between 75th and 51st avenues from 10 p.m. Friday, Feb. 17 to 5 a.m. Monday, Feb. 20. Eastbound I-10 on-ramps at 91st, 83rd and 79th avenues will also be closed.

These closures will allow crews to establish a safe work zone to build an interchange connecting I-10 and the South Mountain Freeway at 59th Avenue. By the time the interchange is complete in late 2019, I-10 will be widened between 43rd and 75th avenues, with additional merge lanes in each direction. In addition, new east-west access roads parallel to I-10 will allow freeway access between 51st and 67th avenues.

The Arizona Department of Transportation selected the weekends of Feb. 10-13 and Feb. 17-20 for the I-10 closures to keep the South Mountain Freeway project moving toward completion by late 2019. The timing also avoids baseball spring training, the NCAA Men’s Final Four Basketball Championship and the recent Waste Management Phoenix Open golf tournament.

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.
