What is the difference between the STP and the STIP?
The Surface Transportation Program (STP) deals with dollars and is one of the major federal highway funding programs. The STP provides the bulk of federal money to the states and the Federal Lands Highway Program. The Statewide Transportation Improvement Program (STIP) is a document that ADOT develops by compiling a three-year project list in cooperation with all federal agencies, COGs, and MPOs as required under TEA-21. All highways and transit projects in the State, funded under Title 23 and the Federal Transit Act, must be included in a federally approved STIP.
