This Executive Summary (separate entity from the comprehensive 2015 Status of Nation's Highways, Bridges, and Transit Conditions & Performance Report to Congress) showcases the highlights of the companion, comprehensive volume. This executive summary contains highlights to the public roadways/highways and Bridges that are part of America's transportation infrastructure. This volume includes an executive summary or synopsis for each chapter included in the comprehensive companion volume. It also contains a significantly reduced number of charts, graphs, and tables with specific data compared to the number available within larger full report. Transportation decision-makers at the municipal, state, and federal level, along with construction and civil engineering executives, and personnel that may be most interested in an overview about America's transportation infrastructure may be interested in this profile resource.

This study gathers information on current practices that senior managers at transportation agencies use to make network-level decisions on resource allocations for their bridge programs. In particular, the study explores how agency bridge management systems are employed in this process. Information was gathered through a review of literature on U.S. and international bridge management, a survey of U.S. and Canadian transportation agencies, and 15 in-depth interviews with state DOT executive and bridge managers.
All phases of road developmentâ€"from construction and use by vehicles to maintenanceâ€"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.
