State Route (SR) 347 Improvement Project ADOT Open House

The City of Maricopa hosted an open house on June 18, 2026, to discuss the State Route 347 Improvement Project led by the Arizona Department of Transportation (ADOT). The project, fully funded, involves a three and a half year construction effort to widen SR 347 by adding travel lanes, constructing grade-separated interchanges at Riggs Road and Mammoth Way, and improving intersections at Casablanca and Maricopa Road. The initial phase starting June 29, 2026, focuses on pavement rehabilitation along the 14-mile corridor from Interstate 10 to the city of Maricopa, with construction primarily overnight and some weekend work. ADOT emphasized safety measures, reduced speed limits in construction zones, and ongoing communication through email alerts and a project website. Questions from attendees addressed project phasing, traffic impacts, lane closures, and enforcement during construction. The project team also highlighted coordination with local agencies and contractors such as Sun Construction and Kimley Horn. No votes or motions were reported, but the meeting served to inform the public and gather feedback on the project schedule and construction impacts.
