Construction of three wildlife underpasses on U.S. Highway 30 south of Montpelier will be completed this fall, improving safety for people while protecting migrating deer and other wildlife.

Bear Lake County Commissioner Wynn Olsen, the Greater Yellowstone Coalition, the Idaho Conservation League, the Idaho Department of Fish and Game, and the Idaho Transportation Department on Tuesday hosted staff from the offices of Sen. Mike Crapo, Sen. Jim Risch, Rep. Mike Simpson, and other regional decision-makers to tour the project to demonstrate the importance of wildlife crossings to public safety and wildlife migrations on Idaho roads.

For years, GYC has advocated for infrastructure on US 20 in Idaho to mitigate wildlife-vehicle collisions and connect fragmented habitat, and a new report highlights the importance of continuing this work. Along the 45-mile stretch from Ashton to the state line, three other sections also landed among the priorities, demonstrating the need to protect this entire corridor.

The Greater Yellowstone Coalition commends the Montana Legislature and Governor Greg Gianforte for listening to Montanans and making important investments and positive steps toward better protecting people and wildlife on our Big Sky highways.

Yellowstone Safe Passages has been surveying roadkill and wildlife for more than four years. While collecting carcass data can be gruesome and disheartening, every data point is helping inform Yellowstone Safe Passages about the areas that see the most accidents – and the areas where wildlife crossings structures will be most effective along Highway 89. This deer will be added to a suite of more than 7,000 wildlife observations collected since the spring of 2020 to help YSP keep wildlife alive and families safe on the road. 

The Idaho Transportation Department recently secured $20.8 million in federal grant funding to build three wildlife underpasses at Rocky Point, a section of U.S. Highway 30 that has an unprecedented number wildlife-vehicle collisions every year. This funding will create safer conditions for drivers and allow one of Idaho’s largest mule deer herds to complete seasonal migrations.

As news spreads that Grizzly bear 399 was struck and killed by a vehicle this week in Wyoming, it’s worth pausing to recognize how a single bruin in the Greater Yellowstone Ecosystem made such an impact on how people connect with the species.  

GYC and the WYldlife Fund teamed up to raise $2.7 million in donations to help keep people safe and wildlife alive along U.S. Highway 26 in Wyoming. This substantial fundraising effort will strengthen the state’s application as it competes for highly competitive federal grant funds.  

After four years of collaborating with partners, meeting with landowners, hosting community workshops and events, collecting data, and investigating tangible solutions, Yellowstone Safe Passages is proud to announce that their proposal for two overpasses at the Dome Mountain priority site along US Highway 89 has been awarded state funding to complete an engineering feasibility study. 

Yellowstone Safe Passages (YSP) is celebrating a milestone in their work toward making Highway 89 safer for people and wildlife. On March 11, 2024, YSP released the US 89 Wildlife and Transportation Assessment to the public. The assessment offers proven solutions for seven areas with the highest rates of wildlife-vehicle collisions and detailed explanations why those sites were identified.
