Daytime travelers using Washington Highway 14 about two miles east of Bingen will need to plan for extended delays starting this week.  Beginning at noon Tuesday, contractor crews working for the Washington State Department of Transportation will fully close the highway for up to 45 minutes at a time, while they work to remove loose, unstable rock from the slope adjacent to the highway between milepost 68 and 69.  Starting Tuesday, work will take place Monday to Thursday for the next three weeks, and delays could occur between 7 a.m. and 5 p.m.  Crews will close the highway at the top of each hour and reopen the highway at 45 minutes past the hour to allow traffic in both directions to clear. These extended closures allow crews to complete more work, shortening the project duration and ensuring the safety of travelers below.  The highway will be open during non-working hours and on weekends.
