PURPOSE & NEED
The primary purpose of this project is to improve safety and mobility for all users and modes of transportation through the approximate 6-mile segment of WY 22 corridor between Jackson and Wilson in Teton County, Wyoming. Currently, travelers experience substantial travel time delays—particularly during the peak travel hours in the mornings and evenings. Existing traffic volumes between the Y intersection and WY 22/390 intersection exceed the two-lane highway capacity. Also, as traffic volumes and congestion have increased over the past decade, the number and severity of crashes have increased. Accessing WY 22 from the local roadway network, particularly making left-hand turns onto and off-of WY 22, is severely inhibited due to congestion.
The list below categorizes the corridor’s transportation needs as either safety or mobility related, although these issues are interrelated. That is, safety problems often affect mobility and vice-versa.
Addressing the Primary Safety Need Through:
- Reducing the potential for crashes, notably related to congestion, turning movements, and wildlife vehicle collisions (WVCs)
- Improving multimodal intersection safety and access
- Improve reliable access for emergency vehicles
- Improving transportation network resiliency caused by natural disasters
Addressing the Primary Mobility Need Through:
- Reducing peak period travel time delay.
- Accommodating existing and future person trips
- Improving multimodal intersection operations
- Support a multimodal transportation corridor.
