The prefabricated steel deck of battledeck floor type was applied to a bridge reconstruction. The work was carried out in four months without stopping traffic. Two loading tests, one during the construction and the other after the completion, and a stress histogram measurement of the bridge were conducted. The load used for the tests was a truck crane with a total weight of 678.2kN. The strain of main girders, longitudinal ribs of the deck and supporting cross beams was measured near the span center. The stress range histogram was measured for four days. Rain-flow method was used to process measured stress. The tests and measurement confirmed that the reconstruction design of the bridge was adequate.
