The Port of Hood River is expecting by the end of the year or early in January to receive notice from the Oregon Department of Transportation requiring a reduction in the weight limit for the Hood River-White Salmon Interstate Bridge from 80,000 pounds to 64,000 pounds for most vehicles, and less than that for some specialized hauling vehicles.  Port Executive Director Michael McElwee points out this would affect specific types of vehicles, like concrete trucks and dump trucks.  McElwee says the weight reduction will come 30 days after the Port receives notice from ODOT.  He adds large trucks account for about seven percent of the traffic that crosses the bridge.
