Major Weekend Closures on Loop 101 and Loop 202; Scottsdale Street Closures Begin for WM Phoenix Open

Weekend Traffic Overview

Valley commuters and weekend travelers should prepare for a high volume of roadwork and event-related closures this Saturday, January 31, 2026. Major stretches of the Loop 101 and Loop 202 are facing full closures for widening projects and utility work, while Scottsdale begins its annual traffic shifts to accommodate the WM Phoenix Open. Drivers are encouraged to plan ahead and allow for significant extra travel time.

Major Freeway Closures and Restrictions

The Arizona Department of Transportation (ADOT) has several significant projects underway this weekend that will impact travel across the metropolitan area:

• North Phoenix: Eastbound Loop 101 (Pima Freeway) is closed between Cave Creek Road and State Route 51 until 5 a.m. Monday, February 2, for a ramp widening project. Additionally, the westbound Loop 101 primary ramp to southbound SR 51 is closed. Detours include using eastbound Union Hills Drive or Bell Road.
• West Valley: Loop 101 (Agua Fria Freeway) will be closed in both directions between Interstate 10 and Thomas Road starting at 9 p.m. tonight through 1 p.m. Sunday for overhead utility line work. Southbound on-ramps at Cardinals Way, Camelback Road, and Indian School Road will also be closed during this period.
• Southeast Valley: Westbound Loop 202 (Santan Freeway) is closed at Arizona Avenue in Chandler for a widening project. This closure extends through Monday morning. The westbound Loop 202 ramp to westbound I-10 is also closed for maintenance, though the HOV ramp remains open.

Surprise and West Valley Updates

In the Surprise area, interchange improvements continue to impact the US 60 (Grand Avenue). While the overnight narrowing of eastbound US 60 and the closure of the southbound Loop 303 on-ramp at Grand Avenue are scheduled to wrap up by 9 a.m. this morning, drivers should still expect residual delays and lane narrowing near 163rd Avenue throughout the day as Phase 2 improvements progress.
