JACKSON, Wyo. — The Wyoming Department of Transportation (WYDOT) is beginning the most thorough level of federal environmental review for a study of WY22 between the Y-intersection and west of Wilson near Fall Creek Road. The project, known as the WY22 Corridor Project, is intended to improve safety and mobility along the highway.

While no final design or alternatives have been chosen yet, the project could include widening the highway, building wildlife crossings and improving pathway safety. In 2025, WYDOT completed activities associated with a pre-National Environmental Policy Act (NEPA) planning process, which allows for the project to advance into the federal environmental review process.

WYDOT is working with the Federal Highway Administration (FHWA) to begin an Environmental Impact Statement (EIS) for the project. “An EIS is the most comprehensive level of environmental review under [federal law],” WYDOT shared in a press release.

Before the EIS can begin, WYDOT has to document why the review is warranted and have the study approved by the FHWA. If approved, the environmental review process will begin later in 2026.

Earlier planning already included information from traffic and safety studies, environmental data collection, five public meetings, a stakeholder group representing Teton County, the Town of Jackson, and local conservation and wildlife interest groups.
