Another truck hit the bridge again today (6/12). This seems to happen about twice a year. The standard yellow bridge height sign does not get their attention. Aside from the damage to the trucks, each time this happens the city spends a lot of resources (two fire trucks and police vehicle out for several hours today). Why not spend little on a big bright red sign - WARNING LOW BRIDGE! Or hang chains before the bridge on both sides like they do in parking garages.
