The Port of Hood River says intermittent single-lane closures of the Hood River-White Salmon Interstate Bridge will begin on Monday, April 8th, and continue through April 12th, between 8:00 a.m. and 3:00 p.m. each day.  The closures will also take place April 15th through the 19th during the same hours.  Crews will be conducting welding repairs on the bridge deck this spring to address increased deck fractures due to heavy truck loads.  Flaggers will direct traffic on the bridge.  Drivers should expect delays of approximately 15 minutes during these hours.  Due to the narrow lanes on the bridge, drivers are strongly advised to proceed slowly and cautiously to ensure the safety of workers.  Additionally, they should refrain from directly looking at the welding arc light when passing through the work zone.
