  • New highways help make connections

    May 13, 2011
    When a new section of highway opens, we here at ADOT celebrate right alongside the local communities, citizens, contractors and stakeholders who all played a part in getting the road built.

  • The Smoothness Factor

    May 4, 2011
    In fact, ADOT goes to great lengths to make sure Arizona’s roads are as smooth as possible…even when that means walking hundreds of miles of roadway! To measure the smoothness of a road, ADOT uses a machine called a profilograph that surveys the road for any lumps, bumps or dips.

  • The Bump in the Road (and how to eliminate it)

    April 28, 2011
    Over the past several years the soil under the Loop 101 travel lanes, where it abuts the bridge over Camelback Road, has been slowly settling and creating a depression.

  • Rubberized asphalt reduces noise, helps environment

    April 21, 2011
    Driving Valley Freeways this time of year? You might hear about or even experience lane restrictions because of rubberized asphalt paving. “Why,” you ask, “does ADOT schedule rubberized asphalt paving between March and May when so many of us are out and about enjoying the gorgeous weather?”

  • On ALERT

    April 20, 2011
    When an ADOT road in the greater-Maricopa County area needs to be closed due to a major crash, emergency or weather-related incident, the Arizona Local Emergency Response Team is put to the task. Otherwise known as ALERT (what a fitting acronym for this team always ready to act!), the group is made up of 10 ADOT maintenance employees who – on top of their regular daytime duties – volunteer to be on-call 24 hours a day, seven days a week to respond to any emergency call.

  • Transportation Planning, part II

    April 19, 2011
    Last week we gave a brief overview of how ADOT plans for future transportation needs through a three-phased approach. We covered the Visioning phase (if money was no object, how would we plan for Arizona’s transportation future) and the Planning phase (given that resources are limited, how should we prioritize the needs identified in the Vision).

  • How to tear down two bridges in 10 hours or less

    April 15, 2011
    In just 10 hours this past weekend, two bridges in southern Arizona were demolished in order to make way for something new. All it took was some good planning, plenty of patience from motorists, a few enormous machines, and a ton of work by crews on the sites.

  • Transportation Planning: From Vision to Program

    April 13, 2011
    Ever try to figure out how ADOT decided to put a freeway where it did? Or why some roads have wider shoulders than others? Well, none of it happened by accident. ADOT, like most transportation agencies, takes a three-phased approach to transportation decision making: Vision, Planning and Programming.
