Joe Heller, our resident engineer on a big project getting underway in the North Valley, joins On the Road With ADOT this week to explain what's coming over the next two and a half years, including a flyover ramp connecting northbound I-17 with Loop 303.
A major component of the work will be building the direct ramps to create the freeway-to-freeway interchange. When completed over the next two-and-a-half years, drivers will skip the traffic signals at the current Loop 303/I-17 diamond interchange.
Engineers at ADOT play a vital role in building and maintaining Arizona’s roads. During National Engineers Week, Feb. 22-28, we’re celebrating engineers and the work they do to keep Arizona moving.
Piers and bridge abutments for the new interchanges at Pinnacle Peak and Happy Valley roads are currently going up, so take a look at some of the work happening right now.
This summer we are rolling out new highway signs to both promote the 511 phone line, attract business sponsorship and generate funds to maintain roads.
ADOT Director John Halikowski explains why everyone needs to realize the importance of infrastructure and protect its value by making investments for the future.
When a pier needed to support a ramp would otherwise need to be in the middle of travel lanes below, ADOT engineers call on this support structure that straddles traffic.
