Tribal Transportation Improvement Program (TTIP)

---

The Federal Highway Administration  (FHWA) Tribal Transportation Program team works in consultation with Tribal Governments to achieve transportation planning on Tribal lands. 

A Tribal Transportation Program (TTP) Agreement between the U.S. Department of Transportation and a Tribe provides an understanding that Tribal Governments inherit "all the functions and duties that the Secretary of Interior would have performed (Chapter 2 of Title 23, USC)." 

As per this legislation, a major planning effort FHWA has approval authority on, in partnership with a Tribe, is the development of an annual TTP Transportation Improvement Program (TTPTIP) derived from a list of eligible projects approved under a Tribe's individual TIP. 

The transportation planning process on Tribal lands as a whole is carried out by the Tribal Government's staff. 

Below are TTIP Drafts for each year in which Navajo DOT has partnered with FHWA.
