The Arizona Department of Transportation (ADOT) announced that a project to add new lanes and make interchange improvements along Loop 101 (Pima Freeway) between Shea Boulevard and Princess Drive/Pima Road in Scottsdale is scheduled to start in early January.

• The $108 million project is scheduled take approximately two years to complete.

Why it matters: This project will widen Loop 101 by one regular traffic lane in each direction within a 4.5-mile work zone.

What you need to know:

• Construction is scheduled to begin with a closure of northbound Loop 101 between Shea Boulevard and Princess Drive from 10 p.m. Friday, Jan. 5, to 5 a.m. Monday, Jan. 8.
• The first weekend closure will allow crews to remove the existing top layer of asphalt pavement and install temporary barrier walls used to set up a work zone along the freeway.
• ADOT is working with the City of Scottsdale to limit restrictions during local special events, including the WM Phoenix Open golf tournament.

We know this construction project will create commuting challenges for our physicians that provide weekend coverage at our medical centers. You provide a tremendous service to our organization, and we thank you for your dedication to meet the needs of our growing community. We appreciate your patience with this process.

Other key elements of the project include:

• Converting the Loop 101 interchange at Frank Lloyd Wright Boulevard into a diamond configuration.
• Turn-lane improvements at the Shea Boulevard, Raintree Drive and Princess Drive/Pima Road interchanges.
• Retaining and sound wall construction.
• Installation of new signs, traffic signals and freeway lighting
