The northbound Loop 101 on-ramp at Shea Boulevard in Scottsdale is scheduled to be closed for about 60 days, starting Monday, April 15.

The closure is necessary for reconstruction work as part of an ongoing freeway widening project, state transportation officials said Thursday.

Drivers should plan on using detour routes and allowing for extra time during the closure, according to the Arizona Department of Transportation.

Detour routes include using northbound Hayden Road or 92nd Street to Cactus Road to enter northbound Loop 101.

Loop 101 on- and off-ramps between Shea Boulevard and Princess Drive will be rebuilt to fit with the wider freeway as part of ADOT’s $108 million project scheduled for completion in early 2026, according to an ADOT release.

The widening project will add 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 into a diamond configuration and the installation of new signs, traffic signals and lighting.
