The Port of Hood River will conduct extensive live load testing on the Hood River-White Salmon Interstate Bridge from Saturday through October 24.  That’s in response to a lowered load rating imposed by the Oregon Department of Transportation in March.  Port Executive Director Michael McElwee says the reduced weight limit on the bridge has had significant impacts on some local businesses, and they want to determine if it is feasible to restore the 32-ton weight limit.  Bridge users should expect intermittent single-lane closures between the hours of 7 a.m. and 5 p.m. every day throughout the testing period, with delays of approximately 30 minutes possible depending on traffic volume.  Flaggers will direct traffic around the moving work zone.  Full bridge closures are anticipated to take place on October 13, 18, and 20, with delays of 30-45 minutes possible.
