  • Building a Freeway: Constructing a temporary bypass

    January 25, 2012
    Remember this awesome time-lapse video showing the construction of a temporary bypass at Greenway Road and the Loop 303?

(Take a look at the photos below for an amazing before and after aerial glimpse of the new bypass!)

    We’re thankful for the approximately 1,570 volunteer groups who currently adopt an Arizona highway. It’s hard to believe, but roughly 335 of the groups have been volunteering for more than 10 years and of those, 50 have been with Adopt a Highway for more than 20 years!

  • Travel demand models help plan for the future

    January 11, 2012
    Short of a time machine, travel demand models might just be the next best thing for taking a glimpse at the future of our transportation system. So, what is a travel demand model?
