  • SR 143 construction surpasses half-way mark

    December 21, 2011
    The improvements to SR 143 are really coming along. In fact, construction now is about 64 percent complete!

  • Attenuators designed to take the impact of vehicle collisions

    December 20, 2011
    Back in July we told you all about truck-mounted attenuators and how vital they are to the safety of ADOT employees and drivers out on the road. But, there’s another type of attenuator that acts on the same principle and does just as much to protect motorists...

  • Quiet Pavement Pilot Program

    December 15, 2011
    Back in the early 2000s ADOT started to hear from drivers who said certain stretches of Valley freeways seemed quieter than others. ADOT and the Maricopa Association of Governments (MAG) noticed a difference, too. It seemed that areas paved with an asphalt rubber friction course (rubberized asphalt), which MAG funded through the Regional Transportation Plan, were less noisy than freeway surfaces with cement concrete pavement.

  • 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.

  • ADOT utilizes GIS to manage information, analyze and plan

    December 13, 2011
    The saying, “a photo speaks 1,000 words” holds true when it comes to data. Because, for most people (we’re not talking about the engineers who are out there reading this!) it’s hard to pull real meaning from just a long list of numbers.

  • 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.

  • Winter weather suspends northern projects for the season

    December 7, 2011
    The official start of winter is approaching, but the cold weather is already here! Over the past few weeks, we’ve told you how ADOT prepares for the snowy conditions common this time of year in Arizona’s high country.

  • 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.

  • State Transportation Board 101

    December 1, 2011
    ADOT’s Long-Range Transportation Plan was formally adopted earlier this month. ADOT planners will now use the Long-Range Transportation Plan as a guide to build a transportation system designed to carry Arizona into the future! But just who is this group – otherwise known as the State Transportation Board – that adopted the plan?
