The Washington State Department of Transportation says people who travel through White Salmon and Bingen using Highway 141 should expect delays for the next couple of weeks.  Beginning Monday, state road crews are using alternating single lane closures for pavement repair work.  Travelers between White Salmon and Bingen will alternate intermittently through a single lane, with flaggers, daily from 6 a.m. to 4:30 p.m. through June 15.  Travelers will follow a pilot car through the work zone and should expect delays of up to 20 minutes when flaggers are present.  Residents in the area are advised that intermittent flashing lights and construction noise may be heard during the repairs.
