Designed to improve traffic flow and safety, a project overseen by the Arizona Department of Transportation (ADOT) and the Federal Highway Administration is making significant progress in Maricopa. Crews are tackling a portion of SR 347 that's widely used and in need of an upgrade.

For the first time, motorists will use a stretch of the future Loop 202 South Mountain Freeway, in this case through a temporary configuration that will allow work to progress on the 17th Avenue and Desert Foothills Parkway interchanges in Ahwatukee. Effective Feb.

The Loop 202 South Mountain Freeway has its first splash of color, with a little inspiration from Frank Lloyd Wright. Crews recently gave the future 40th Street traffic interchange in Ahwatukee desert earth-tone base paint, which will be used throughout the 22-mi.

Playing the part of a transportation planner isn't always easy, especially when it comes to balancing priorities for Arizona's highway system with the realities of limited funding. When the Arizona Department of Transportation turned to the public and stakeholders last fall to tell us what's most important to them over the next 25 years, nearly 6,000 people statewide responded through a quick and interactive online survey.

It turns out that some types of wildlife like to go over a state highway, others tend to go under it and still others can go either way. Those are initial results of a survey of camera-monitored usage of a new $9.5 million wildlife crossing of State Route 77 near Oro Valley in northeastern Pima County.

Three Arizona Department of Transportation employees working to keep highways open in recent storms avoided serious injury when vehicles struck two ADOT snowplows in separate crashes. The drivers of the other vehicles came out fine as well. One of the plows wasn't so lucky, however, when a semi rear-ended and severely damaged it Jan.

Sensors installed at three Interstate 40 locations west of Flagstaff are helping the Arizona Department of Transportation forecast the likelihood of ice forming and respond accordingly. The combination of freezing temperatures and moisture means ice can form overnight in Arizona's high country.

Over the past year, the Arizona Department of Transportation asked the public and agencies to share their ideas, comments and concerns about the Interstate 11 environmental study from Nogales to Wickenburg. A summary of comments is now available and will help ADOT select and evaluate corridor alternatives for further study.

To protect driver safety, the Arizona Department of Transportation (ADOT) is moving a mountain on the north side of Interstate 40, about 6 mi. (9.65 km) west of Holbrook. The I-40 Rock-Fall Mitigation Safety Project began in January on westbound I-40 near Joseph City.

Second phase construction is under way on an ambitious $1.77 billion project to construct a 22-mi. (35 km) freeway loop to connect the east and west valleys in the greater Phoenix area. The Loop 202 South Mountain Freeway is Arizona's largest single highway project ever.

The Arizona Department of Transportation launched a contest Monday to determine the next overhead sign safety message. From "Hello from the other side, buckle up and stay alive," to "Don't turn your car into a Death Star, Drive focused," ADOT has featured these creative and unusual signs for over a year.
