Marking an important step to safeguard both people and wildlife, the bipartisan infrastructure package that the U.S. Congress passed today includes $350 million to construct wildlife road crossings.

ARC Partner and Advisor to the 2010 ARC International Wildlife Crossing Infrastructure Design Competition, Professor Nina-Marie Lister, has been named the 2021 Margolese Prize Winner for her leadership in urban ecology and design. The prize celebrates a Canadian citizen who has made a significant contribution to the built environment and the people within it.

Discover wildlife crossing success stories across North America featuring a diversity of species, from toads to pronghorn to mountain lions; a range of landscapes, from urban to rural and in between, and learn about the partnerships that came together to make our roads safer for people and wildlife. 

Developed collaboratively by a multidisciplinary team of experts, this report summarizes for policymakers the challenges and anticipated benefits of creating a systematic, national network of wildlife crossings.

Wildlife overpasses, or structures that bridge a road or highway to allow wildlife to cross over safely, pay for themselves fairly quickly but are often regarded as expensive to build. This report contains information useful to transportation engineers, compiling design and construction techniques, strategies, and considerations aimed at reducing costs while maintaining or improving the efficacy of wildlife overpasses.

This publication features answers to the most common inquiries and misconceptions regarding wildlife-vehicle collisions and the proven success of wildlife crossing infrastructure in solving this ubiquitous problem. Often, the available scientific literature, peer-reviewed publications, and technical resources are long, complex and not easily digestible. Developed in collaboration with leaders in the scientific research and implementation of wildlife crossings, the most current and accurate information has been distilled in a question and answer format.

ARC is absolutely thrilled to be part of the outstanding collaboration working to ensure that the crossing at Liberty Canyon represents a worldwide model of excellence in design for the safe passage of people and wildlife, making it both a physical and symbolic bridge to the future for southern California’s wildlife including its treasured mountain lions.

(Re)Connecting Wild tells the remarkable story of the decade-long effort by the Nevada Department of Transportation (NDOT) and its partners to improve human safety by re-connecting a historic mule deer migration that crosses over both US-93 and I-80 in rural Elko County, Nevada. Witness the wildlife crossing structures along I-80 from construction to the restoration of safe passage for migratory mule deer to more than 1.5 million acres of summer and winter habitat.

Highways & Habitats is an online introduction to Road Ecology – the interaction of transportation systems and infrastructure with wildlife and habitats.  Presented by the Vermont Agency of Transportation (VTrans) and the Vermont Fish & Wildlife Department (VF&WD), Highways & Habitats Tier 1, gives a broad overview of the Road Ecology challenges and opportunities for transportation and wildlife professionals.

ARC is an interdisciplinary partnership working to facilitate new thinking, new methods, new materials and new solutions for wildlife crossing structures. Our goal is to ensure safe passage for both humans and animals on and across our roads. Situated at the intersection of science and design, we are a forum for creative collaborations and surprising synergies.
