Bridges are structures designed to support traffic and other dynamic loads induced by vehicle loads to pass through natural or manmade obstacles. Types of pathways may be roads, highways, railroads, pipeline waterways, or pedestrians. Obstacles can be categorized as canals, rivers, mountains, valleys, lakes, seas, and other manmade structures, such as buildings, rail lines, roads, and bridges themselves. A bridge is a vital structure of modern roadway and railway systems and largely serves as the lifeline of public infrastructure. Apart from bridge structures, Roads and highways are commonly considered important to new-fashioned life and they play an important role in the advancement of cities. The lack of quantifiable sustainability methods creates gaps in sustainability knowledge, leading to the public, and environmental and financial dissatisfaction with completed highways and urban roads. This chapter discusses the key points in design and construction assessment of bridges, highways, and roads covered in the present book in order to bridge the knowledge gap. The discussed topics such as bridge optimization techniques, risk assessment of roads, highway management systems, and challenges in highway construction presented in the book chapters help to provide insights into the bridges and roads’ impacts on the environment and the benefits of adopting development assessment systems to increase safety of bridge structures, roads, and highways.
