Selecting the proper location for a bridge is as important as determining the characteristics of the bridge itself. This report discusses a commonsense approach, combined with science, to help select sustainable locations for bridges. Problems associated with bridge location and construction can be minimized by conducting a proper site investigation, paying attention to geomorphic indicators, knowing trail design needs, and understanding how streams and watersheds function. Channel classification provides a simple framework to help land managers understand the potential problems that may exist at bridge locations. An interdisciplinary approach is required to incorporate all the considerations involved in choosing the best bridge location for sustainability.
