Corrosion Monitoring Research for New York City Suspension Bridges

The objective of this research is to develop and deploy either innovative non-destructive testing (NDT) technologies (Direct Sensing Method) for detecting corrosion damage and/or by installing corrosion sensing technologies to monitor the internal environment of the main suspension cables (Indirect Sensing Method). The project has three phases: Phase I shall consist of identifying appropriate sensing technology, data recording and processing equipment, and making a mock-up to verify the measurement system configuration. Phase II will be a follow up project to transfer the technology from the laboratory to field. An appropriate bridge platform shall be identified for this field study in the future by FHWA based on the recommendation from Phase I. Phase III will include additional field testing, collection of field data and modification of sensors and algorithms as needed.
