Project Overview

ADOT, 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.

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 34,000 vehicles per day and future (2030) projections show up to 69,000 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 west of the intersection and vehicular traffic is routinely delayed for its passenger operations.
