The Historic Columbia River Highway will be closed next week for rockfall work near the Oneonta Tunnel east of Multnomah Falls. Starting Sunday crews will begin scaling the hillsides adjacent to the tunnel to bring down loose rocks. The hillside was burned during the 2017 Eagle Creek Fire, destroying vegetation and increasing the threat of rockfall. Work is expected to begin at 8 a.m. Sunday with flaggers controlling traffic around the tunnel. At 4 p.m. Sunday the Historic Columbia River Highway will be closed around-the-clock to all users between Multnomah Falls and Interstate 84 exit 35 at Ainsworth State Park. The road will reopen by 8 p.m. Friday, Feb. 28. The Eagle Creek Fire badly damaged the tunnel, a part of the Historic Columbia River Highway State Trail. The rockfall work is needed to begin the process of repairing and reopening the tunnel.
