On February 25, Road Ecology Program Manager Rob Ament was a guest on Top of Mind with Julie Rose, a BYU Radio program. For a feature segment on wildlife crossings, Rob discussed how crossing structures are designed, how they make roads safer for both animals and motorists, and where the newest structures are being built, both in the U.S. and globally. The full Wildlife Crossings interview is available to stream on the BYU Radio website.
In 2018, the Utah Department of Transportation completed the state’s largest wildlife crossing, which traverses six lanes of traffic on Interstate 80. The crossing structure made the news again last week, when research footage captured deer, moose, elk, bears, bobcats and a variety of smaller mammals using the bridge. In news coverage by Smithsonian Magazine, “Animals are Using Utah’s Largest Wildlife Overpass Earlier Than Expected,” WTI Road Ecologist Rob Ament is quoted regarding the high percentage of collision reductions that typically occur after the installation of crossing structures. Rob’s quote is also included in a similar article by Nature World News.
The U.S. Forest Service has released a new report authored by wildlife crossing experts from WTI, ARC Solutions, and other partner research organizations, which compiles key guidance information that may lead to the installation of more wildlife crossing structures.
Wildlife crossing structures are one of the most effective means of reducing animal-vehicle collisions on highways, while facilitating essential animal movement across the landscape. Yet the widespread implementation of such structures, especially wildlife overpasses, has been hindered by cost concerns. In 2014, WTI hosted a workshop in partnership with ARC Solutions and prominent wildlife crossing experts from Canada and the United States to determine whether there are design parameters and construction techniques that could be added, changed, or adjusted to reduce costs, while maintaining or improving the effectiveness of wildlife overpasses.
Concepts identified during the workshop were developed into specific strategies. This document presents 32 potential cost savings considerations, which were consolidated into three categories:
- design and construction
- procurement, delivery method, and cost accounting considerations

On October 20, ARC Solutions presented former WTI Director Steve Albert with a Lifetime Road Ecology Leadership Award in recognition of his enduring legacy in making our nation’s roads safer for both people and wildlife.A not-for-profit network working to promote leading-edge solutions to improve human safety, wildlife mobility and landscape connectivity, ARC celebrated Steve’s leadership, his encouragement, and his creativity, first as a co-founder of the ARC International Wildlife Crossing Infrastructure Design Competition and then as an original member of the ARC Steering Committee. Executive Director Renee Callahan highlighted a variety of successes supported and inspired by Steve during his decade-plus tenure with ARC, including:
“Winning 4 Wildlife” – Aimed at introducing middle school students to the concepts of safe passage and the need for creative wildlife-friendly solutions to make our highways safer, this curriculum was co-developed by three Montana teachers as part of WTI’s Innovative Transportation Systems Research Engagement for Teachersprogram in 2018.
WVC Reduction and Habitat Connectivity Pooled Fund Study – ARC partnered with the State of Nevada to launch a pooled fund study on WVC Reduction and Habitat Connectivity. Study members, including Alaska, Arizona, California, Iowa, Michigan, Minnesota, New Mexico, Oregon, Washington, the Ontario Ministry of Transportation and Parks Canada, have since committed $1.275 million in research funds to identify cost-effective solutions to integrate highway safety and human mobility with wildlife conservation and habitat connectivity. WTI Road Ecologist Marcel Huijser is leading a team of researchers conducting the research task to identify and evaluate cost-effective strategies.
Fiber-Reinforced Polymer Crossing Structure – In one of the research projects under the Pooled Fund Study, WTI is teaming with ARC Solutions, Ryerson University and the California Department of Transportation to explore design-based opportunities to build North America’s first fiber-reinforced polymer (FRP) wildlife crossing in Siskiyou County, CA. A highly-versatile materialthat is durable, modular, and virtually maintenance free, FRP is widely used in Europe for bike-ped infrastructure and promises to be a game-changer in the construction of the next-generation of wildlife infrastructure in the U.S.
During the ceremony, ARC presented Steve with a keepsake card and commemorative print by renowned wildlife photographer Joe Riis depicting mule deer crossing a roadway within the Greater Yellowstone Ecosystem. Family, friends, and colleagues joined in the festivities by sharing personal and professional tributes illustrating Steve’s exceptional leadership within the field of road ecology. ARC is fiscally sponsored by the Center for Large Landscape Conservation in Bozeman, MT. To learn more about ARC’s work, please visit arc-solutions.org.

WTI Road Ecologist Rob Ament is featured in a recent issue of Time Magazine for Kids. A feature article called “Safe Travels” describes the large number of animals that are killed in roadway collisions each year, and how wildlife crossing structures work to protect animals as they move across their habitats. Rob discusses successful designs – like the crossing structures in Banff National Park – and how they are models for new efforts around the world, including a project he is working on in Kaziranga National Park in India.
Time for Kids is a weekly magazine for elementary school children. It offers age appropriate learning material for students and is designed to complement curriculum.
Conservation groups – including the National Wildlife Federation, Save L.A. Cougars, and ARC (Animal Road Crossings) – marked Wildlife Crossings Week (May 4 – 8) by hosting a series of webinars on current efforts around the world to enhance habitat connectivity. Road Ecology Program Manager Rob Ament led a session on “Improving Ecological Connectivity: the IUCN’s Transport Working Group,” highlighting his collaborative work with the International Union for the Conservation of Nature. Rob’s full presentation is available to view on the event’s Facebook page.
Did you miss the Earth Optimism Summit hosted by the Smithsonian last month? It also showcased successful conservation actions during a multi-day event. WTI Research Scientist Marcel Huijser led a workshop entitled “Road Ecology – are we taking the right turns?” His presentation is now available to view at on the Summit website.
WTI Researchers are collaborating on a research project to develop, implement and evaluate a wildlife crossing structure made of Fiber-reinforced polymers (FRPs), a strong but lightweight composite material that could significantly reduce the construction and maintenance costs of wildlife overpasses and associated infrastructure elements. In recent project news, an FRP wildlife crossing will be designed for a location on US Highway 97 in Siskiyou County, California – the first of its kind on this continent.
The project has evolved out of several research collaborations at WTI. In May 2018, WTI and its partners, Ryerson University in Toronto, Canada, and ARC (Animal Road Crossing) Solutions hosted a design collaboration laboratory (Co-lab) on FRP-based wildlife crossing structures. The Co-lab engaged experts in engineering, landscape architecture, and ecology from across North America and set the stage for further exploration of FRP material use in wildlife crossing infrastructure.
Also, in 2019 WTI was selected to lead a team of researchers for a Transportation Pooled Fund Study (PFS) administered by the Nevada Department of Transportation and co-sponsored by the State Departments of Transportation of AK, AZ, CA, IA, MN, NM, OR, and WA, as well as Ontario’s Ministry of Transportation and Parks Canada Agency. The FRP structural design, implementation and evaluation will be conducted as part of the Pooled Fund Study. Marcel Huijser is the PI for the overall Transportation Pool Fund Study, which will identify a range of cost-effective solutions to reduce wildlife-vehicle collisions. Matthew Bell, Damon Fick and Rob Ament are leading the FRP design project component; Mat had the opportunity to present a poster on FRP research at the TRB Annual Meeting in Washington, DC in January 2020.
The Idaho Transportation Department is currently considering wildlife crossing structures for a segment of U.S. 20 near Island Park. High Country News recently published an extensive feature article exploring both support and opposition to this proposal: “When wildlife safety turns into fierce political debate.” WTI Road Ecologist Marcel Huijser was interviewed for the article, discussing the potential role and effectiveness of animal detection systems. The article also cites his research on the costs to society of vehicle crashes with deer and other large mammals.
One of the country’s leading newspapers consulted a WTI researcher and several of our road ecology publications for a national feature story on wildlife crossings. “Retrofitting busy highways to let wildlife travel safely, too” explored national and state initiatives to identify wildlife corridors and enhance crossing structures such as underpasses and overpasses. The Post interviewed Road Ecology Program Manager Rob Ament, who discussed the potential long-term genetic consequences of highways that restrict wildlife movement and connectivity. The article also cites WTI/Montana Department of Transportation research on wildlife crossings on US 93 in Montana, and a cost-benefit analysis study that documented the direct and indirect costs of collisions with large animals.
The Jackson Hole News and Guide has published “Bridging a future for wildlife,” a feature article on proposed wildlife crossings structures for Wyoming highways. In the article, WTI Road Ecology Program Manager Rob Ament discusses how crossing structures can be highly effective in reducing collisions between vehicles and large mammals, especially if the locations are carefully sited and the structures are designed to meet the needs of the target species. WTI has conducted wildlife mitigation planning in Wyoming; Marcel Huijser, Rob Ament and the rest of the Road Ecology team collaborated on the development of the Teton County Wildlife Crossings Master Plan, completed in 2018.
