# §170.424. What is the TTP Transportation Improvement Program (TTPTIP)?

- (a) Each year, FHWA will compile the approved TTIPs for all of the Tribes into one document called the TTPTIP. This document will identify all expected projects and activities over a four-year period and will be organized by fiscal year, State, and Tribe.
- (b) FHWA and BIA will post the approved TTPTIP on their respective Web sites. A subset of the TTPTIP that identifies only design and construction activities will annually be provided to the pertinent FHWA Division office for further transmittal to each State Transportation Office/Department for inclusion in the STIP without further action per [23 U.S.C. 201(c)(4)](/usc/23/201.md?p=c-4).
