The Oregon Department of Transportation is working to get I-84 reopened, but it may be another week before the eastbound lanes re-open.
ODOT has removed about 2,000 trees that were in danger of falling onto I-84 with about 1,500 remaining to be removed. Tree removal efforts should be finished by early in the coming week.
The biggest impediment to re-opening the highway is the threat of falling rocks, most of them around the Toothrock Tunnel. The work is slow in steep, difficult terrain extending high up onto the hillside.
ODOT inspected 70 bridges and culverts along I-84 and found minimal damage.
Tunnels. An inspection of the 1936 Toothrock Tunnel on I-84 showed minimal rock damage to portals. The liner inside the Oneonta Tunnel on the HCRH completely burned and engineers found unstable rock slopes at each end.
In the weeks ahead, ODOT will be assessing the danger of winter slides in areas where the underbrush has burned away.
The Historic Columbia River Highway remains closed with no schedule to reopen. Rocks and trees continue to fall; ODOT is working to keep the highway available for firefighters, but the highway is not safe for travel.
