The southbound Loop 101 on-ramp at Cactus Road will be closed for about 60 days starting early Monday, Aug. 26, state transportation officials said Thursday.

The ramp will be reconstructed as part of a freeway widening project in north Scottsdale, according to the Arizona Department of Transportation.

Drivers who normally would use the ramp should plan on using an alternate route, including entering southbound Loop 101 via the on-ramp at Shea Boulevard.

The $108 million Pima Freeway improvement project between Shea Boulevard and Princess Drive/Pima Road started in January.

Over the course of the two-year Loop 101 project, on- and off-ramps between Shea Boulevard and Pima Road/Princess Drive are being reconstructed to fit with the wider freeway. The entire project is scheduled for completion in early 2026, according to ADOT, which is adding one lane in each direction along 4.5 miles of the Pima Freeway north of Shea Boulevard.

Other improvements include converting the Frank Lloyd Wright Boulevard interchange to a diamond configuration and installing new signs, traffic signals and lighting, officials stated in an ADOT release
