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.

It’s not just about building and maintaining roads; transportation is what connects people, businesses and our communities. We think it’s pretty important and want to take a chance to briefly describe how transportation is funded in this state.
For obvious reasons, highway work zone safety is a serious subject here at ADOT… The agency’s employees who build and maintain Arizona’s roadways are constantly aware of (and prepared for) any hazardous situation that might occur.
When more than 200 horses and their riders want to cross the freeway, it’s smart to move out of their way! It also is a good reason to close the road to vehicle traffic, which is what happened twice this week when US 60 and US 93 were shut down briefly at the south roundabout in downtown Wickenburg.

We don’t know about you, but the Loop 303 improvement project sure has taught us lot about building a freeway… So far, we have come to understand more about soffit fills and waste slabs than we ever thought possible. We’ve also learned quite a bit about false work and sand jacks, bridges, temporary bypasses, caissons and even dirt.
