Just like counties and municipalities, Nebraska's tribes are part of Nebraska LTAP's service mission. They also have access to a regional Tribal Transportation Assistance Program providing similar programs. The Northern TTAP Center is at North Dakota State University.
The Northern Tribal Technical Assistance Program (Northern TTAP) provides transportation outreach and technical assistance to tribes across the Upper Great Plains and Intermountain West. The program works with American Indian tribal governments to build tribal capacity in program management, grow the tribal workforce, cultivate and coordinate partnerships, facilitate technology transfer and the implementation of innovations, and share results of similar initiatives across the country.
The program is a collaboration led by the Upper Great Plains Transportation Institute at North Dakota State University and includes the Western Transportation Institute at Montana State University, as well as South Dakota State University, and the University of Wyoming.
