While certain spot locations may require minor capacity, the general capacity of the highway is adequate for current and future traffic volumes. In addition, a segment of US 191 and WYO 351 require safety improvements. Additional mobility options will become more important in future years in the Jackson area to accommodate recreational and commuter traffic with public transportation and associated facilities. Plans should include the rehabilitation and replacement of deficient bridges. CORRIDOR CHARACTERISTICS Corridor Description The Rock Springs to Jackson corridor is a heavily traveled 175 mile route in western Wyoming. Identified as State Significant Corridor (SSC) 4, it connects Interstate 80 (I-80) on the south at Rock Springs (population 20,200) to the town of Jackson (population 9,806) on the north. The corridor spans a region of diverse geography and economies. The high plains area to the south has been heavily developed by extractive energy interests across agricultural and public lands, primarily Bureau of Land Management (BLM). North of Pinedale, the corridor transitions to mountainous terrain, with some agriculture, and a vibrant recreationally-based tourism industry centered on the Grand Teton and Yellowstone National Parks, as well as the Bridger-Teton National Forest. The section from Pinedale to Jackson includes part of the Centennial Scenic Byway. The type of travel is largely dependent on the surrounding land uses, and whether the traffic is local, regional, or just passing through. Truck traffic and oil field service dominates the traffic mix to the south, while recreational travelers use the corridor as a major access to the national park area north of Jackson. The Jonah Field and the Pinedale Anticline in the Green River Basin west of US 191 between Pinedale and Marbleton represent two of the most active oil and gas fields in the state. Corridor Interests: Blowing and drifting snow affects winter travel, especially south of Pinedale, while deeper snowfall accumulation affects the northern end of the corridor.

ÑTourism and recreation travel, both to points along the corridor and to the national parks to the north, is expected to continue at historic levels. While US 191 is not the most traveled route to Yellowstone, it is an important connection. Providing adequate services to these travelers is an important part of the State’s image. ÑThe north end of the corridor, from Hoback Junction to Jackson carries a high volume of traffic. The traffic mix includes commuters working in the service and recreation industries as well as visitors. Recreational traffic is significant in all seasons and peaks during the summer months. ÑThe corridor has challenging blowing and drifting snow and snow removal issues, including avalanches in mountainous areas. While District 3 puts a high priority on these activities, the high costs erode expenditures on other improvements. ÑWildlife mortality and the costs associated with vehicle/wild animal crashes are a problem the length of the corridor, but especially high north of Pinedale.
