All phases of road development—from construction and use by vehicles to
maintenance—affect physical and chemical soil conditions, water flow, and air and water
quality, as well as plants and animals. Roads and traffic can alter wildlife habitat, cause
vehicle-related mortality, impede animal migration, and disperse nonnative pest species of
plants and animals. Integrating environmental considerations into all phases of
transportation is an important, evolving process. The increasing awareness of
environmental issues has made road development more complex and controversial. Over
the past two decades, the Federal Highway Administration and state transportation
agencies have increasingly recognized the importance of the effects of transportation on
the natural environment. This report provides guidance on ways to reconcile the different
goals of road development and environmental conservation. It identifies the ecological
effects of roads that can be evaluated in the planning, design, construction, and
maintenance of roads and offers several recommendations to help better understand and
manage ecological impacts of paved roads..
