The Port of Hood River is recommending motorists avoid the Hood River-White Salmon Interstate Bridge on Thursday between 9 a.m. and 3 p.m. as electrical and engineering crews work to re-commission newly installed electrical controls and systems for the bridge lift span.  Delays of an hour or more are anticipated, as the work entails testing and troubleshooting any issues as they arise, there is no set schedule for the closures.  Port Executive Director Michael McElwee says they will try to open the bridge if possible during the work, but they can’t guarantee it.  McElwee adds motorists will be turned around at the Highway 14 and south of the toll booths to prevent vehicles from becoming stacked up on the bridge.
