Passenger Rail Study: Tucson to Phoenix

ADOT has been working closely with the Federal Transit Administration, the Federal Railroad Administration and local governments and planning organizations in Maricopa, Pinal and Pima counties to determine which routes would move forward for further study. The decision to pursue these three alternatives came not only from technical evaluations, but was also largely based on public input. During the last two years of the study, nearly 7,000 people across Arizona completed surveys to weigh in with their ideas of which routes best served communities.

Ultimately ADOT's passenger rail line will be designed as a blended service: An express service would have few stops between Phoenix and Tucson and a local service would stop at several communities along the way.

There is currently no construction schedule and no funding identified for a project to build a rail system between Phoenix and Tucson. It will be up to the public and policymakers to decide if the project is feasible and how to generate the funding to pay for the project.

Seven Alternatives Narrowed to Three

ADOT continues to study the feasibility of a passenger rail line between Phoenix and Tucson and has narrowed the list of alternatives to three. ADOT is moving forward with the Green Alternative, which would run along Interstate 10 between the two metropolitan areas; the Orange Alternative, which would serve the East Valley and share part of its alignment with the planned North-South Freeway Corridor; and the Yellow Alternative, also serving the East Valley but sharing right of way with Union Pacific Railroad. All three alternatives would run along I-10 south of Eloy in to Tucson.
