There will be intermittent, single-lane closures of the Hood River-White Salmon Interstate Bridge next Monday through Friday between the hours of 9:00 a.m. and 3:00 p.m.  They will take place to allow for semi-annual bridge deck welding.  Port crews and crews from Bulldog Welding will be on the bridge performing weld repairs to the bridge deck, as well as replacing and repairing sections of guardrail.  Flaggers will be on the bridge directing traffic.  Motorists should expect delays of approximately 15 minutes during these hours.  As the bridge’s narrow lanes create a very compact work zone, motorists are urged to drive slowly and with caution for worker safety.
