Work on the approach ramps to the Port of Hood River Interstate Bridge is about to get underway.  Port Executive Director Michael McElwee says contractor Wildish Construction is staging today, and work should start on Tuesday, and there will be delays on weekdays for about three weeks between 6 a.m. and 6 p.m.  McElwee says repaving is being done on approach ramps on both the Oregon and Washington sides of the Columbia River.  Work is expected to continue through August 8.  McElwee indicated there would be about four overnight closures of the bridge during this construction period, to be scheduled at a later date.
