The Historic Columbia River Highway from Bridal Veil to Ainsworth State Park and Interstate 84 Eastbound exit 41 off-ramp at Eagle Creek will both remain closed until at least Wednesday due to debris slides Sunday during heavy rainfall. The Oregon Department of Transportation says the highway closure is due to a debris slide from heavy rainfall feeding Mosquito Springs Creek. About 70 cubic yards of material had blocked the highway by 4 a.m. Sunday between Angel’s Rest and Multnomah Falls.
