Both convenient and easy to use, a new pocket guide available from the Federal Highway Administration's (FHWA) Resource Center offers a portable reference for bridge inspectors. Stream Instability, Bridge Scour, and Countermeasures: A Field Guide for Bridge Inspectors provides tips and guidance on what to look for with regard to both stream instability, including lateral instability, degradation, and aggradation, and scour at bridges, including contraction scour, pier scour, and abutment scour. Also covered are plans of action and countermeasures, such as monitoring, flood watches, bridge closures, and river training countermeasures.
