Highlights

Drivers heading through Scottsdale and the broader Phoenix area this weekend face a series of freeway closures and lane restrictions as the Arizona Department of Transportation runs concurrent improvement projects from Friday night through Monday morning, May 29 to June 1.

The most direct Scottsdale impact: the Pima Freeway section of Loop 101 narrows to two southbound lanes between Princess Drive and Shea Boulevard from 10 p.m. Friday to 5 a.m. Monday. ADOT says on- and off-ramps in both directions in that corridor will close at times and advises drivers to budget extra travel time. Southbound I-17 is the recommended alternate.

Southbound SR 51 closes entirely between Indian School Road and I-10 in Phoenix over the same window, 9 p.m. Friday to 5 a.m. Monday, for a pavement improvement project. On-ramps at Glendale Avenue, Bethany Home Road, and Highland Avenue also close. ADOT recommends southbound I-17 for drivers heading to downtown Phoenix or Sky Harbor Airport.

The Agua Fria section of Loop 101 adds northbound lane closures between I-10 and Indian School Road in Glendale for the same Friday-to-Monday stretch, part of the Loop 101/I-10 interchange improvement project. Northbound 91st Avenue or 99th Avenue to Indian School Road are the suggested surface-street detours.

Eastbound Loop 303 between 43rd Avenue and I-17 closes overnight Friday (9 p.m. to 8 a.m. Saturday) and again Saturday night (9 p.m. to 8 a.m. Sunday) for a widening and interchange project. The same overnight closure pattern continues nightly from Monday evening through Saturday morning, June 6. Detour: northbound 43rd Avenue to eastbound Dove Valley Road to I-17. ADOT also closes two of five northbound I-17 lanes between Dixileta Drive and Loop 303 from 4:30 a.m. to 2 p.m. Sunday.

In south Maricopa County, SR 347 at Riggs Road closes intermittently for up to 15 minutes at a time from 4 a.m. to 4 p.m. Sunday while crews work on utility lines and traffic signals ahead of the SR 347 Improvement Project, which ADOT says is set to begin this summer.

The closures were confirmed by azcentral and AZFamily. Full detour maps are posted at azdot.gov. All lanes are scheduled to reopen by 5 a.m. Monday, June 1.
