PHOENIX – The Arizona Department of Transportation opened a new northbound Loop 101 lane between Shea Boulevard and Princess Drive Monday morning.

The lane in Scottsdale is part of a $108 million improvement project to assist traffic flow along the freeway.

Crews put in place lane stripes and removed barricades over the weekend. There are now four general purpose lanes and a high-occupancy vehicle lane open along northbound Loop 101 between Shea Boulevard and Princess Drive/Pima Road.

ADOT plans to open a new southbound lane along the 4.5-mile project work zone following a Nov. 7-10 weekend closure between Princess Drive and Shea Boulevard, state transportation officials said.

The Loop 101 Improvement Project started in January 2024 and is set to be completed early next year.
