  • 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!

  • From start to finish: How ADOT builds a freeway

    October 4, 2011
    When ADOT builds a road, the work gets started years (sometimes decades) ahead of any real construction … It all begins with the planning phase, which includes everything from determining where a new roadway is most needed to taking a look at available funding.

  • Loop 303 makes annual "Top 10 Roads" list

    September 15, 2011
    When the editorial team at Roads & Bridges makes choices for the magazine’s annual Top 10 Roads list, many factors are considered. But, according to Editorial Director Bill Wilson, it’s the challenges faced in building each nominated road and the project’s impact that get the closest looks. Maybe that’s why the Loop 303 (Happy Valley Road to Lake Pleasant Parkway) made it to this year’s top 10!

  • “Turnin' dirt” on the Loop 303 in Surprise

    August 11, 2011
    Think back to 1984. You might recall that the United States hosted the summer Olympics in Los Angeles and Michael Jackson’s Thriller snagged eight Grammy Awards. It’s also when the Maricopa Association of Governments (MAG) identified the need for a West Valley regional connector freeway later to be dubbed Loop 303.

    May 13, 2011
