(Troutdale, OR)  --  Transportation officials say the Interstate 84 will remain closed for at least another week while crews clean up damage from the Eagle Creek Fire.  Officials say they're still clearing fallen trees and rocks from the roadways.  They're also working on making sure bridges, tunnels and hillsides are safe in the area.  Meanwhile, the Coast Guard has reopened the Columbia River to all traffic after the fire prompted them to enact a safety zone last week.
