Rendering of model ADOT is using as a guide for engineers designing the overpass on SR 347 over the Union Pacific Railroad tracks.

Beginning next week, Arizonans will be able to provide input on the Arizona Department of Transportation’s update of projects proposed to move forward in the next five years and how much local, state and federal funding should go toward those projects.

In its Tentative Five-Year Transportation Facilities Construction Program for 2017-2021, ADOT was able to recommend a few more projects because of additional funding through the Fixing America’s Surface Transportation (FAST) Act, as well as a Transportation Investment Generating Economic Recovery (TIGER) grant. These projects otherwise would have remained in ADOT’s Development Program for projects deemed six to 10 years out.

After the public comment period, which includes public hearings in Oro Valley (March 18), Phoenix (April 15) and Flagstaff (May 20), the State Transportation Board will make its final decision in June about what will be in the updated Five-Year Program.

Among ADOT’s suggestions to move forward on a quicker timeline is the State Route 347 railroad overpass project in Maricopa. That project received a $15 million TIGER grant and a $15 million local contribution to add to ADOT’s $19 million commitment.

The list also includes two Interstate 10 widening projects in Pinal County (State Route 87 to Picacho Peak and Earley Road to Interstate 8) and two widening projects along US 93.

“Increased funding opportunities, particularly through the FAST Act, have allowed ADOT to propose accelerating some expansion projects in Greater Arizona that, once complete, will enhance key freight corridors for the movement of commerce,” said Michael Kies, director of ADOT’s Multimodal Planning Division. “Some of these projects are also critical to the overall implementation of the future Interstate 11, which will open the door to greater economic opportunities and competitiveness for our state.”

Arizona’s existing highway system is valued at more than $20 billion. ADOT’s proposal meets its goal of $260 million per year dedicated to preservation work, such as bridges in need of upgrades and pavement in need of repair.

The 2017-2021 Tentative Program will be available for public review and comment at azdot.gov/fiveyearplan, where a “how to read it” guide is available. ADOT welcomes feedback through Survey Monkey at surveymonkey.com/r/CJY36HY, email at [email protected] and by calling 1-855-712-8530. The comment period ends at 5 p.m. on May 30.
