On June 6, 2013, ADOT, in conjunction with the Federal Highway Administration and the City of Maricopa, held an alternatives overview public meeting at the Maricopa Unified School District from 6:00 p.m. - 7:30 p.m.

At this meeting, the project team:

  • Reviewed the study's purpose and need.
  • Provided an overview of considered alternatives.
  • Discussed the evaluation criteria.
  • Presented the alternatives being recommended to move forward as the study progresses.

There was an open Q&A and any comments received or postmarked by June 21, 2013, were included in the Public Record for this project.

State Route 347 is Maricopa's main transportation corridor through the community, serving as a regional connector to major employment and recreation areas. Traffic averages over 34,000 vehicles per day and future (2030) projections show up to 69,000 vehicles per day. Just south of the Maricopa- Casa Grade Highway, SR 347 crosses the existing UPRR where there are currently 40-60 trains per day; the UPRR has plans to expand service, which would increase train traffic upwards of 100 trains per day. Additionally, the Amtrak station is located just west of the intersection and vehicular traffic is routinely delayed for its passenger operations.

The Arizona Department of Transportation, in conjunction with the Federal Highway Administration and the City of Maricopa, initiated a study to evaluate alternatives and identify improvements to access, capacity and traffic operations through 2040. The study is evaluating a future grade separation (bridge) to replace the existing at-grade intersection of SR 347 at the Union Pacific Railroad (UPRR) track.


Your thoughts, opinions and ideas are important to ADOT. We encourage public participation and look forward to hearing from you by phone or email.
