The Choshi Bridge has been exposed to sea breeze over 40 years. At present, this bridge is suffering corrosion at the several truss panel points apparently. First of this paper,the traffic control of this corroded truss bridge is examined by numerical simulation. And secondly, for the earthquake occurrence, the important points to be inspected are suggested by time-history response analysis. Simulation results show the usefulness of the inspection of floor beams at the panel points.
