Cars on US 60
A couple months ago we told you how ADOT works to minimize the noise impact a new freeway has on surrounding neighborhoods. Well, similar efforts also are made when it comes to air quality …

When prices at the pump started to spike a couple years ago, ADOT began looking at ways to cut fuel costs for the 4,200 vehicles in its fleet. And, believe it or not, the idea for a very promising solution came from the roof of a pretend cop car … well, sort of.
Bridge in Northern Arizona
Much has changed since ADOT got its start in 1927. Back then, the agency was known as the Arizona State Highway Department and roads certainly were built a little differently. Methods, materials and technology have changed so much since then.
Trash on the side of the freeway
Last month we told you about the thousands who take on the immense task of cleaning up Arizona’s roads through ADOT’s Adopt a Highway program – more than 800 tons of trash is picked up off the state highways each year because of these volunteers!
Construction of a Sound Wall
Most people don’t find the sound of traffic especially soothing … ADOT certainly recognizes this and is constantly working to minimize the impacts to surrounding neighborhoods from the noise of new freeways.
Construction of an HOV Lane
Crews are busy adding more than 80 lane miles of high occupancy vehicle (HOV) lanes to two Valley freeways – 30 miles in both directions on Loop 101 in the west Valley and 12 miles on east- and westbound Loop 202 in Chandler that will link directly to HOV lanes on the Loop 101 (Price Freeway) and Interstate 10.

It’s a sad truth, but trash thrown onto our state’s roadways really adds up. That’s because it’s not just a few random soda cans, cigarettes or empty bags littering the roads and surrounding areas. In reality, more than 800 tons of trash gets picked up in Arizona each year.

ADOT can’t just construct a freeway wherever and however it wants… Building a road actually requires a lot of careful planning, thought and exploration long before the first construction crews ever arrive on site.
