Project Purpose and Need

The purpose of this project is to provide travel redundancy and improve multi-modal connectivity between South Park neighborhoods and areas accessed by WYO 22, including Wilson, Teton Village, other West Bank neighborhoods, and eastern Idaho. Currently, drivers making these connections must travel through the Y intersection of US Highways 26/89 and WYO 22, adding to the congestion at this major crossroad. This poor connectivity limits options for improved transit services as well as emergency service to affected neighborhoods in West Jackson and parts of Teton County, including Boyles Hill, Cottonwood Park, Indian Trails, 3 Creeks, Teton Science School, and Teton County School District #1 campuses.

The Project Purpose and Need and Objectives statement have been updated to incorporate feedback provided by the Project’s Stakeholder Advisory Committee.

Community needs that would be addressed by this project include:


Project Objectives

Project objectives supplement the Purpose and Need and the alternatives screening process by helping to differentiate between alternatives. Whereas an alternative must meet the Purpose and Need, project objectives are used to further identify which alternative best meet the needs, avoids and minimizes environmental impacts, and could realistically be implemented given constructability and funding constraints.

  1. Safety – To improve emergency vehicle access and provide route redundancy in and around West Jackson and South Park.
  2. Environmental Protection – To reduce VMT and vehicle emissions; avoid and minimize impacts to other environmental resources.
  3. Cost Effectiveness – To reduce VMT and thus reduce travel delay and costs for the community.
  4. Roadway Network Compatibility – To provide network redundancy to reduce local trips through the Y intersection, and to minimize delays caused by maintenance operations and crashes on US-26/89 and WY-22. These events can isolate the Town from Teton Village, Wilson, and other West Bank areas.
  5. Multimodal Function – To provide more direct, safe, aesthetically pleasing, and efficient multi-modal routing (for START transit services, school buses/vans, cyclists, and pedestrians) between South Park and the West Bank. To improve access and opportunities for active transportation mode choice.
