PHOENIX – The northbound Loop 101 on-ramp at Raintree Drive has closed for about 60 days, state transportation officials said.

The ramp, which was closed late Sunday night, will be reconstructed as part of a freeway widening project in north Scottsdale.

Drivers who normally would use the ramp should plan on using an alternate route, including entering northbound Loop 101 at Frank Lloyd Wright Boulevard, according to the Arizona Department of Transportation.

ADOT asks Loop 101 drivers in the area to allow extra travel time, slow down and to continue to provide room for traffic entering the freeway while crews work on the widening project. 

The $108 million Pima Freeway Improvement Project between Shea Boulevard and Princess Drive/Pima Road started in January 2024. The project is adding new lanes in both directions and providing other improvements, including enhancements at the Frank Lloyd Wright Boulevard interchange. It is scheduled for completion in early 2026, according to an ADOT release.
