When you’re building bridges, there’s more than one way to get the job done... We told you a few months ago about a method that utilizes false work and sand jacks. Today, we’re going to fill you in on a different approach … the key terms to remember are soffit fills and waste slabs.

Bigger, easier-to-read signs are coming to a freeway near you! That’s because at the beginning of the year, ADOT adopted the latest edition of the Manual on Uniform Traffic Control Devices (MUTCD), along with the Arizona supplemental modifications, as a standard for traffic control devices for use on the streets and highways of the state of Arizona.

Last week we were asked on Facebook to provide an update on the Loop 303 project – specifically the bridge construction at Waddell Road. We’re happy to oblige! We also are glad to report that the bridge construction is progressing as planned.

When Arizona turned 100 last month, we celebrated by documenting everything ADOT does across the state in a single day. And, oh what a day it was!

Something kind of cool came across our desk and we wanted to share … The Metropolitan Phoenix Chapter of WTS – an organization aimed at advancing women in transportation – sent out a news release that says two Arizona students and their mentors are headed to Washington DC to meet federal officials and take part in some key transportation-related events, including the DC Youth Summit.

What does the phrase “going green” mean to you? If you work in one of ADOT’s Equipment Services shops, it means implementing more than 175 environmentally conscious “best management practices” within your workplace.

Arizona’s transportation system has evolved over the past 100 years from a series of unpaved roads into a robust network of highways, airports and transit systems equipped with the latest technology and innovations.

When you see signs directing you to tune in to a certain radio station for construction information, do you ever wonder where the signal is coming from? Chances are a nearby Highway Advisory Radio transceiver is helping to deliver the message.

ADOT’s efforts to ease some of the stop-and-go traffic on Grand Avenue have been pretty successful so far, but you don’t have to just take our word – we’ve got the results to prove it! Before we reveal those findings, let’s back things up a bit first …

Just last month we blogged about a project that’s under way on I-17 and SR 69 in Cordes Junction. So, maybe you’re wondering why we’re bringing it up again so soon … Well, we’re blogging about it today because we’ve got an awesome new video (see above) that details the entire project and shows footage from January when crews installed some precast girders – a milestone in the construction.
