The Port of Hood River has received a report on the biennial fracture critical inspection of the Hood River Interstate Bridge, and it includes a problem exacerbated by overweight trucks using the bridge.  Port Executive Director Michael McElwee says they have known about the issue with the four connection points at the auxiliary trusses installed when the lift span of the bridge was installed in the late thirties.  McElwee notes the Port Commission will consider an engineering contract to develop the plans and specifications to make the repairs, adding bridge inspectors have indicated trucks weighing over the 80,000 pound bridge limit are accelerating problems with the structure.  McElwee says many of the trucks using the bridge are local, and said the Port needs to communicate better with those operators the impact overweight vehicles have on the bridge and its ability to be maintained over a long period of time.
