Summary In this study, in order to apply open grating deck to general highway bridges, wheel load running test, exposure test and cost estimation were carried out. The wheel running test focused on the detail of the intersection of girders under grating deck. In the exposure test, the influence of water leakage on corrosion was set as parameter. The cost estimation was based on trial design for the general road bridges.
