Teton Pass Corridor & ITD Traffic Study
March, 16 2023
The U.S. Forest Service, Teton County, Wyoming and the Wyoming Department of Transportation have collaborated to produce a draft Teton Pass Corridor Management Plan. In addition, although it is not mentioned in the Corridor Management Plan, IDT is strongly considering adding a 70 mph passing lane between Victor and Mike Harris. If wildlife are funneled into Idaho - as stated in the plan - through mitigation measures in Wyoming (wildlife fencing), there will be an increasing threat to both human life AND wildlife. This is part of why it is so critical that wildlife mitigation not stop at the state line.
An article in written by Jared Baecker, Wyoming Conservation Coordinator states: "According to Jackson Hole Wildlife Foundation’s citizen-collected data from 1991 to 2020, 439 wildlife-vehicle collisions have been documented on Teton Pass. It has been confirmed that 243 mule deer and 157 moose have been killed by vehicles in the 3.75 miles between the Coal Creek trailhead and the Wyoming-Idaho state line. WYDOT traffic counts, reported wildlife-vehicle collisions, and recreational visits are all trending up. The bottom line is wildlife are being squeezed." Where will these animals cross if fencing ends at the state line?
The draft management plan is open for public comment until Friday March 17th.
