The STIP is revised annually. The first step is a series of RPO meetings held with all local, tribal, state and federal government entities, and other interested parties. Current program rules and transportation issues are discussed. Public transportation projects are reviewed and prioritized by RPOs also. The STIP is then finalized and approved by the Highway Commission.
Rural transportation is supported by federal, state, and local funds.
The State Road Funds and federal funds are generally used to improve and maintain the State Highway System. The Local Government Road Fund, comprised of dedicated tax revenues, provides support to counties, municipalities, school districts, and other entities for developing projects, and improving and maintaining local roads. This support is distributed to local entities by statutory formula. BIA and FHWA directly administer some rural transportation funds. Counties and municipalities receive dedicated revenues from the state legislature, some dedicated for roads and streets and some for general use.
