LOWER SNAKE RIVER, Wash. – If your upcoming Veterans Day weekend plans include a road trip to visit family and friends on the opposite side of the lower Snake River, you may want to keep in mind that most U.S. Army Corps of Engineers dams are closed to cross-dam public vehicle traffic on federal holidays, unless otherwise announced. The legal public holiday for Veterans Day 2017 – Nov. 11 – falls on a Sunday. For most federal offices, Monday, Nov. 12, will be treated as a holiday.
