State Transportation Improvement Program (STIP)
State Transportation Improvement Program (STIP)
All highway and transit projects in the state, funded under Title 23 and the Federal Transit Act, must be included in a federally approved STIP. Projects in the STIP must be consistent with the statewide long-range transportation plan and metropolitan transportation improvement programs (TIPs). The program must reflect expected funding and priorities for programming, including transportation enhancements. Additionally, the Clean Air Act Amendments (CAAA) requires Metropolitan Planning Organizations (MPOs) within nonattainment areas to perform conformity determinations prior to the approval of their Regional Transportation Plans (RTPs) and TIPs.
These conformity determinations show that the Current STIP. As a product of all the regional TIPs, is consistent with the air-quality goals in the applicable Arizona State Implementation Plans (SIPs).

Arizona Tribal Transportation Improvement Program
The following document is the Federal Fiscal Year 2024 Arizona Tribal Transportation Improvement Program, also known as the "TTIP." It includes all construction projects in currently approved TTIPs in the state. The funding reflected in the document is provided by the federal TTIP program and not by the State of Arizona. The TTIP is a companion document to the Five Year Construction Facilities Transportation Program, but is approved by the Federal Highway Administration instead of the State Transportation Board.
