  • 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? Well, today we’ve got an even more in-depth look at how crews built the new intersection – complete with temporary barriers, fences and traffic signals – in just about 43 hours! (Take a look at the photos below for an amazing before and after aerial glimpse of the new bypass!)

  • Partnering 101

    January 20, 2012
    When ADOT builds a freeway, there is an essential step that surprisingly requires absolutely no construction or even heavy lifting. We’re talking about partnering – the ADOT and construction industry process that allows everyone on the project to get together, set goals and talk about the work ahead.

  • Work starts on Loop 303/I-10 interchange

    If you’ve been following our Building a Freeway series, you should be pretty familiar by now with much of the work that’s happening out on the Loop 303.

  • ADOT takes a look back at 2011

    January 3, 2012
    The new year officially is here, but before we dive into 2012 we’re going to take a quick look back. ADOT’s Public Information/Media Relations team came up with a great list of the state’s major transportation accomplishments from 2011 and we thought we’d share it here on the blog!

  • New 303/Greenway construction bypass built in 43 hours

    December 14, 2011
    Accommodating existing traffic is a key priority when ADOT builds a freeway … Depending on the project, that can mean working out a construction schedule that takes rush hours into account or hiring extra crews to flag and direct traffic through the site.

  • Loop 303/Greenway intersection closure slated for this weekend

    December 8, 2011
    Crews are going to move a lot of dirt as they widen Loop 303 in the West Valley. But, at one intersection, there’s a crucial bit of work that needs to get done before they can start digging! This weekend the Loop 303/Greenway Road intersection in Surprise will be closed beginning 10 p.m. Friday so crews can quickly re-align the intersection, install a temporary traffic signal and temporary sidewalk.

  • Building a Freeway: Moving Dirt

    December 6, 2011
    Before you can build a freeway, you’ve got to move a little dirt... Make that a LOT of dirt, especially in the case of the Loop 303 project under construction right now in the West Valley.

  • Building a Freeway: Sand Jacks and False Work

    November 17, 2011
    Last month, as part of our Building a Freeway series, we told you about the massive underground support substructures that help give bridges strength. Next up in the series is an important -- but temporary -- structure that’s used as crews build a bridge, tunnel or even a box culvert.

  • Building a Freeway: Massive underground caissons give bridges strength

    October 21, 2011
    You know when you drive under or over a freeway bridge that it’s a massive structure… There are the two abutments (the upright supporting structures at each end that carries the load of the bridge span), there are usually center columns or piers, and, of course, the girders and the bridge deck (the part you actually drive across).

  • Building a Freeway: Pre-wetting the soil leads to solid foundation

    October 5, 2011
    When ADOT has a freeway to build, many steps must be taken long before any asphalt is paved. One of those initial tasks involves pre-wetting the soil, which entails pretty much exactly what you think it does … crews put sprinkler systems into place and water the dirt!
