Welcome to the Yankton County Master Transportation Plan web page. Yankton County, along with South Dakota Department of Transportation (SDDOT), is sponsoring the development of this planning study. The study will examine current transportation issues and needs facing Yankton County and decide how best to address them. All transportation modes will be studied, including roadways, transit, railroads and freight, and pedestrian and bicycle facilities. When completed, the study will outline recommended improvements and provide a plan for implementing them. The goal is to create a livable community that will enhance the economic and social well-being of all Yankton County residents and travelers.

About the Study :

The study will consist of three main phases to be completed over a 12-month period:

  • The first phase will inventory and analyze existing and future conditions and identify the problems and needs.
  • The second phase will develop strategies, alternatives and potential solutions that address the problems and fulfill the needs. Because of limited budgets for transportation infrastructure maintenance and construction, costs will be considered when developing alternatives.
  • The third and final phase will select alternatives for further study and prioritize them based on planned investments for Yankton County

Study Area

The study area includes the incorporated and unincorporated cities and townships of Yankton County, with the exception of the City of Yankton.

Public Involvement

An important component of this master transportation planning study is your input. We want to know about your travel patterns, your destinations and the challenges you face getting there. As the study progresses, we will need your input on the potential alternatives we develop for improving our area's transportation network.

The South Dakota Department of Transportation (SDDOT) has a long history of public involvement in the development of transportation plans and projects. The 2012 passage of the Moving Ahead for Progress in the 21st Century Act (MAP-21) requires a public involvement process. In accordance with the Department's public involvement plan document, the Yankton County Master Transportation Plan Study strives to keep the public involved with the study as much as possible.

Public Meetings

Public meetings for the study will occasionally be scheduled to collect public input, provide information and answer questions.

Public Meeting #1 - June 16, 2014

Public Meeting #2 - December 3, 2014

Public Meeting #3 - March 23, 2015

Stakeholder Group Meetings

Municipalities and certain business types often have aspects that can have unique impacts to a county’s transportation system that can be more thoroughly discussed outside of the public meeting format. As such, stakeholder groups consisting of representatives from the municipalities, large employers, and active trade and transportation oriented organizations within Yankton County will be invited to a set of stakeholder meetings that will be held throughout the study period.
