Welcome to the South Mountain Freeway information site!
The Loop 202 (South Mountain Freeway) adds 22 miles of freeway to the existing Phoenix metropolitan transportation system. The freeway connects the east and west valley while providing much needed relief to existing freeway corridors and local streets.
Here you will find everything you need to know about the project – whether you are interested in project history, the new shared-use path, media, or simply receiving construction updates to stay in the loop.
The next time you’re riding in the passenger seat or back seat down the Loop 202 South Mountain Freeway, or perhaps another freeway closer to you, take a few minutes to gaze out of the window. But don’t look at the mountains or a beautiful sunset. Instead, look at the colorful designs on the bridges, ramps and sound walls. Look at the plants too.
An ADOT team creates designs for a freeway based on either the history or the current use of the land. If you drive over the Salt River on the South Mountain Freeway, you can see images that look like waves of water passing over desert rocks. In the West Valley, the South Mountain Freeway designs are inspired by the area’s agricultural past. In Ahwatukee, the freeway's designs are inspired by Frank Lloyd Wright, one of the greatest architects in American history. He once worked in that area.
ADOT also decides which plants and other landscaping accents will help make a highway beautiful.
The video at right shows you designs and the landscaping along the 22-mile South Mountain Freeway.
But what if those walls, bridges and ramps were blank? What would you draw on them? Would they be animals or saguaros? What plants and colored rock would be in the landscaping? This ADOT Kids activity asks you to make those choices and create your own freeway designs.
It isn't just the South Mountain Freeway with neat designs. The new State Route 87 interchange with Interstate 10 between Phoenix and Tucson has designs inspired by cotton grown in that area. In Tucson, sound walls at the new Ajo Way interchange with Interstate 19 have images of mountains and saguaros that speak to that area's landscape. If you need more inspiration, the slideshow at right has images of highway designs around the state.
Not everyone is fortunate to have beautiful designs on walls and bridges. The first time my dad came to Arizona, he was surprised by images of desert plants on the sound walls that separate the freeway from buildings. Near his home in Ohio, freeway walls are just that: a gray concrete wall with no decoration.
Fortunately, in Arizona we use freeway designs to help tell the story of an area.

Print out the coloring sheet and draw your own freeway design!
Make a freeway beautiful using the coloring sheet linked here and posted at bottom right. Or draw your own from scratch. Add your own designs and colors. Pick and locate plants. Will you use decorative rock? All of the choices are up to you.
Here some interesting freeway fun facts ...
The freeway looks like it’s all concrete, but it includes enough steel rebar weighing 40 million pounds. That's about the same as 3,100 elephants!
To build the freeway, we moved enough dirt to fill State Farm Stadium, where the Arizona Cardinals play, six times!
Ever heard of a chuckwalla? They’re small lizards that lived on South Mountain. We moved about 120 of them to keep them safe during construction. Here's a video of the relocation.
How did the jackrabbit cross the road? There are five crossings under the freeway where people and animals can get safety from one side of the road to the other.
