The Project
The new Pinnacle Peak Road overpass is now scheduled for completion in late May, 2020. It will have two through lanes and two left-turn lanes in each direction.
The new Happy Valley Road overpass should be finished two months later. It will be a “diverging diamond traffic interchange,” or DDI, involving two parallel bridges, with three lanes in each direction, in a setup ADOT says will improve traffic flow and safety [See “The Roundabout is Out,” Aug. 10, 2017.]
As part of the project, I-17 will be widened between the two interchanges from four lanes (including the HOV lane) to five in each direction. Expect a few more delays at both interchanges, while those new lanes are paved, through the end of October 2020, ADOT has told North Phoenix News.
