What is the public private partnership and how does it benefit taxpayers?

A P3 refers to the contractual agreement between a public agency and a private sector entity to have greater participation in the delivery of a transportation project. By securing a P3, the entire SMF project can be constructed as one project rather than nine, as originally scheduled, which accelerated project delivery by at least three years. For additional information on the P3 process please visit the P3 Initiatives page.

How was the freeway funded and built?

The freeway was funded by state, federal and local dollars. It is not tolled. The final design, construction and 30-year maintenance of the freeway occurred through a public-private partnership (P3) agreement with C202P. This P3 not only expedited construction, but also reduced the overall cost. This project would have cost an estimated $100 million more than it did if ADOT had not utilized a P3 and the design-build project delivery method.

How is dust controlled?

Dust control is always a priority for the construction team. Keeping the soil moist during ground-disturbing activities is the most effective means for preventing dust. Water spraying and soil stabilization materials are used in all construction areas before, during and after construction activity.

How will construction noise be reduced?

There are two primary sources of noise during major construction activities: equipment engine noise and back-up alarms. While the construction team understands these alarms can be disruptive to nearby residents, they are a vital safety feature proven to reduce the number of construction fatalities. OSHA requires the alarms to be used and to be audible above the surrounding construction noise.
