The Seneca Nation of Indians has a proud and rich history. We are the largest of six Native American nations comprising the Haudenosaunee or Iroquois Confederacy or Six Nations, a democratic government that pre-dates the United States Constitution.

We are known as the "Keeper of the Western Door," for the Seneca are the westernmost of the Six Nations.  In the Seneca language we are also known as O-non-dowa-gah, (pronounced: Oh-n'own-dough-wahgah) or "Great Hill People."

Today, the Seneca Nation of Indians has a population of over 8,000 enrolled members. We are the fifth-largest employer in Western New York, creating thousands of new jobs and investing hundreds of millions of dollars to bolster the region's and New York State's economy.

We invite you to explore our website to learn about our rich culture and traditions, our diverse and strong sovereign economy and the quality of life that makes us proud to be Seneca. 


Rickey L. Armstrong Sr., President, Seneca Nation of Indians

The Seneca Nation Department of Transportation (SNDOT) is seeking comments on the Seneca Nation’s Tribal Transportation Improvement Program (TTIP).

The TTIP is an annually updated list of proposed multi-year transportation projects developed by the Seneca Nation. Projects are determined from the Tribal priority list and/or the Long Range Transportation Plan (LRTP), for use of Federal Lands Highway Tribal Transportation Funds. The current list of projects are Transportation Planning, Road Maintenance, Pennsy Trail (to be completed fall of 2019), Route 438 Safety Improvements, Ohi:yo’ Gateway (to be completed summer of 2019), Seneca One Stop Services Center (formally the I-90 Oasis Project), Lenox Road (Completed and to be removed from the TTIP), Red House Bridge / Old Route 17, Casino Access Road, Response (s) to Declared Emergencies as needed.

The SNDOT is encouraged to consult, as appropriate, with regional and local transportation agencies and Seneca Nation agencies responsible for land use management, natural resource management, environmental protection, conservation, and historic preservation in the development of transportation plans and programs. 

The TTIP is the complementary capital-programing component of the LRTP. It consists of federally funded roadways, public transit systems, multi-modal trails, transportation safety, and major transportation projects and enhancements being considered within, and providing access to, the Seneca territories over the next five (5) years. 

The SNDOT is updating the Nation’s TTIP to include:

  • Intersection safety improvements along the Broad Street (Route 417) corridor with great concern to the Broad Street and Iroquois Drive Intersection. The department is seeking grant funds through the Federal Lands Highway Tribal Transportation Program Safety Funds (TTPSF). 
  • Jimersontown Walkability
  • Safety Plan
  • Marshals Safety Data Collection
  • Allegany DPW Access Road

Please submit any comments by May 17, 2019. Comments may be submitted to SNDOT Project Manager, Sharon Ray, by mail or email at the following:

Department of Transportation, 90 Ohi:yo’ Way, Salamanca, NY 14779
