Tribal communities are vulnerable by unsafe and often inaccessible roads, bridges and ferries. There are aging and unsafe bridges that are used for economic development for Tribal nations and to transport children to school that are in need of improvement. Failing infrastructure is not only inconvenient but causes financial constraints on our families. Since our infrastructure is our economic foundation, it is beneficial that we improve it to allow for increase in our gross domestic product, jobs and our connections with our international markets. When we observe our infrastructure, we understand that most of our problem is hidden, and we don't notice it until it is inoperable. When we focus our attention on solutions our infrastructure will improve.

The TTP Bridge Program is focused on improving the number of TTP bridges in poor condition. This information has been created to assist our partners working to improve the condition of BIA/Tribally owned bridges and non-BIA/Tribally owned bridges.

Federally recognized Indian Tribes may submit an application at any time for eligible TTP bridges for planning, design, engineering, preconstruction, construction, and inspection of new or replacement bridges; replace, rehabilitate, seismically retrofit, paint, apply calcium magnesium acetate, sodium acetate/formate, or other environmentally acceptable, minimally corrosive anti-icing and deicing composition; or implement any countermeasure for TTP bridges classified as in poor condition, having a low load capacity, or needing highway geometric improvements, including multiple-pipe culverts.
