In addition to a week filled with blogs and social media posts that celebrate engineering and engineers, this episode of On the Road With ADOT features Audra Merrick, ADOT's State Engineer and Deputy Director.

As we mark National Engineers Week, let’s introduce you to where the action happens: ADOT’s State Engineer’s Office, led by State Engineer and Deputy Director Audra Merrick.

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.

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.

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.
