Data were generated for the project "Data-centric Bridge Assessment - The Marsh Lane Bridge." PI: Prof. Matthew DeJong, University of California, Berkeley. Co-funded by The Alan Turing Institute and Cambridge Centre for Smart Infrastructure and Construction.

Data have been collected with a 4-channel sm130 Optical Sensing Interrogator of Micron Optics, Inc., permanently installed in the bridge, as described in the paper.
