Abstract
As global road networks continue to expand, the resulting habitat fragmentation poses a significant threat to wildlife populations and ecological connectivity. In the United States, wildlife-vehicle collisions (WVCs) account for approximately 10 million animal deaths and 40,000 human fatalities annually, with incidents increasing by 50% over the past 15 years. This research investigates the ecological impacts of transportation infrastructure through a case study of Interstate 10 in Louisiana, specifically a 15-mile segment between Sorrento and LaPlace that cuts through the Maurepas Swamp Wildlife Management Area. This forested wetland, home to a rich diversity of species including the American alligator, has no safe crossing corridors for wildlife, leading to increased mortality and disrupted ecological processes. Focusing on the American alligator as a representative species, this study combines roadkill inventory data, spatial analysis, and conceptual design to propose a wildlife crossing intervention. The project aims not only to mitigate local impacts but to establish a repeatable design framework for reconnecting fragmented habitats globally. Ultimately, the research supports ecological restoration while honoring and preserving Louisiana’s cultural and environmental heritage.
