An additional seven miles of the Historic Columbia River Highway will close during the day starting at 8 a.m. Wednesday to ensure the health and safety of State Parks staff and the general public.  Last week, the Oregon Department Of Transportation closed the Historic Highway from Angel’s Rest to Ainsworth, a seven mile section of road, around the clock.  All of the Historic Columbia River Highway State Trail has been closed since last month.  On Wednesday, a seven-mile section from Larch Mountain Road to Angel’s Rest will close every day from 8 a.m. to 8 p.m.  Vista House, Multnomah, Horsetail, Shepperd’s Dell, Wahkeena and Latourell falls and other recreation destinations in the corridor remain closed twenty-four hours a day, seven days a week.  An ODOT statement said crews along the road see more than 200 vehicles an hour with many visitors violating barricades, some throwing closure signs off the road and many trespassing into closed parks and trails. In addition, official crews in the area report contacting visitors about once every four minutes while trying to maintain the closure of recreational facilities.  The new closure points will be staffed by the Oregon Parks and Recreation Department.  Access for local residents and emergency services will be maintained.
