With ADOT's State Route 347 at Union Pacific Railroad project well underway, this page will provide local news and information related to the project to help keep residents informed. If you have any questions or concerns about the project, please call our Overpass Tracker Hotline at 520-316-6910.

Project Overview

SR 347 is Maricopa's main transportation corridor through the community, serving as a regional connector to major employment and recreation areas. Traffic averages over 31,000 vehicles per day and future (2040) projections show over 60,000 vehicles per day. Just south of the Maricopa-Casa Grande Highway, SR 347 crosses the existing UPRR where there are currently 40 to 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 east of the intersection and vehicular traffic is routinely delayed for its passenger operations.

ADOT, in conjunction with FHWA and the City of Maricopa, completed a study to evaluate alternatives and identify improvements to access, capacity and traffic operations through 2040. The study evaluated a future grade separation (bridge) to replace the existing at-grade intersection of SR 347 at the Union Pacific Railroad (UPRR) track.
