The Maricopa Association of Governments has announced plans to undertake a two-year, $225.5-million project to widen and improve the Loop 101 Pima Freeway in northern Phoenix and northern Scottsdale.
The project, which will extend along the Loop 101 from Interstate 17 in Phoenix to Pima Road in Scottsdale, will include additional lanes in each direction to address congestion issues at major points along the freeway, including I-17, State Route 51, Cave Creek Road and Tatum Boulevard.
Sections of the Loop 101 Pima Freeway see as many as 215,000 vehicles per day and the freeway is an important conduit for traffic to and from the Scottsdale Airpark, which is the second-largest employment center in the region, according to MAG.
Freeway improvements will also include the installation of rubberized asphalt, or quiet pavement, drainage improvements and technological upgrades.
The State Transportation Board is expected to consider the Arizona Department of Transportation’s recommendations and award the design-build contract for the project at its Dec. 21 meeting.
The project will also include the construction of the Miller Road underpass in northern Scottsdale to provide an additional street connection between the north and south sides of the freeway.
Nationwide is planning to construct a portion of an extension of Miller Road in conjunction with Cavasson, the 134-acre mixed-use project the company is building at Hayden Road north of Loop 101.
The underpass is included in the City of Scottsdale’s 2018/19 Capital Improvement Plan at a total cost of just over $20 million.
The city’s adopted budget allocated $19,543,700 to the Miller Road underpass project, with $13,680,600 coming from regional sales tax funds from Maricopa Association of Governments’ Arterial Life Cycle Program.
In 2004, voters in Maricopa County approved Proposition 400, which allowed for the continuation of a 0.50 percent regional sales tax through 2025 to fund transportation projects.
Another $5,863,100 will come from the City of Scottsdale’s transportation sales tax.
