Modern Inspection Practices for Culverts and Storm Drain Systems

The latest of TRB's National Cooperative Highway Research Program (NCHRP) Ready Results explores new technologies and practices to inspect culvert and storm drains. The manual assists transportation agencies with incorporating culverts into modern asset management systems—a move that allows agencies to improve the way they prioritize rehabilitation activities and more clearly demonstrate the need for repair funding. The manual provides guidance to help agencies reduce costs and improve safety by addressing issues early, before they become severe.
