There will be a single-lane closure on the Hood River-White Salmon Interstate Bridge on Thursday from 9 a.m. to 2 p.m. as Port crews work to repair potholes on the approach ramp. Flaggers will direct traffic around the work zone, and delays of about 20 minutes should be expected. Due to the close proximity of the work area to Washington Highway 14, motorists may experience delays or traffic backups on the highway as well.
