To what extent does small terrestrial wildlife use crossing structures? TRB hosted a webinar on Thursday, August 12, 2021 from 2:00-3:30 PM Eastern that identified how small mammals, reptiles, and amphibians use road passages and barriers. Presenters provided case studies and lessons learned in North America. They also discussed other considerations that need to be accounted for with practical implementation of road barriers and passages.

This webinar features research from an NCHRP project, Road Passages for Small Terrestrial Wildlife: Summary and Repository of Design Examples. For more resources on the topic, see TRB’s blog post Protecting Wildlife Habitat is a Robust Slice of Transportation Planning.
