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.

We like to check in, from time to time, on the Loop 303 project… Over the past two years we’ve been able to see a 14-mile stretch of the freeway open to traffic, witness the start of construction on new segments and mark many, many milestones along the way.

Yes, paving on N20 has begun, but drivers shouldn’t plan on using the route as a detour until construction is completed later this summer.
We’re loving all the Haboob Haikus that have been rolling in this week… Like last year, this poetry challenge with the funny name has helped us accomplish an important goal, which is to get people talking about the danger of driving in dust storms. Because we cannot forget that dust storms can pose very real risks to motorists in this state – just take a look at the video above for proof.
Last year, ADOT launched its very first “Haboob Haiku” challenge in an effort to spread the word about dust storm safety and the response was pretty amazing. That’s actually a huge understatement ... Not only did we receive over 600 original haikus (some even by phone and snail mail), but #HaboobHaiku yielded stories in media outlets all over the world (they even wrote about it in New Zealand!).
