The United States Army has over two hundred steel bridges in its inventory; virtually every Army Installation has at least one steel bridge.  A number of these steel bridges are considered Fracture Critical, a condition in which failure of a single component (due to phenomena such as corrosion) could cause the entire bridge to collapse.  Bridge failure issues are mitigated through regular inspection of the structure, which includes visual, dye penetrant, ultrasonic, and/or radiographic nondestructive test methods.  These methods are capable of detecting most defects of concern to bridge authorities, but some of these methods may not detect cracks in members that are completely hidden, and none of them are able to determine (in a single measurement) if a defect is actively growing.  As a result, standard bridge inspection techniques may not detect those cracks that are likely to compromise bridge integrity, and could instead focus attention on cracks that, while readily detectable, may be harmless relative to the overall structural health of the bridge.  This paper will describe an effort to incorporate state-of-the-art and emerging sensor technology approaches into a comprehensive, integrated, remote structural health and corrosion degradation monitoring system for military steel bridges.  It is anticipated that such a system will significantly reduce the risk of a catastrophic failure, by providing advance warning of a growing structural problem caused by corrosion/material degradation as well as an opportunity for repair before such a failure can occur.
