South Mountain Freeway crews are making tracks on the project that will add 22 miles of freeway to the Valley, working simultaneously in different areas.

This Art of Transportation photo is from construction on one of two bridges over the Salt River that will be part of the new freeway. The heavy construction equipment visible in the background left an interesting pattern in the dirt.
