Phase 2 of restoration begins in late 2020

The Oneonta Tunnel after the 2017 Eagle Creek Fire.

Restoration work is needed to reopen the Oneonta Tunnel on the Historic Columbia River Highway State Trail after the Eagle Creek Fire. Crews will restore the tunnel, including the wood lining beginning late 2020.

Schedule

• Phase 1: Rockfall scaling on the hillsides adjacent to the Oneonta Tunnel -- complete in February 2020.
• Phase 2: Restoring the tunnel -- Late 2020 through summer 2021.

Schedule subject to change.

Construction Impacts

Travelers should expect single lane closures on the Historic Highway with flaggers directing traffic near the Oneonta Tunnel. Most work will occur during daylight hours on weekdays and no traffic impacts will take place on weekends.

History

The 125-foot Oneonta Tunnel originally opened in 1914 as part of the Historic Columbia River Highway. In 1948, ODOT redirected traffic around the tunnel onto its current location on the highway and filled the tunnel with rubble. In 2009, ODOT restored it for bicycle and pedestrian use as part of the Historic Columbia River Highway State Trail.

The 2017 Eagle Creek Fire badly damaged the Oneonta Tunnel’s wood lining. Now, fire recovery work is needed to safely reopen the tunnel.

Rock scaling, the first phase of work, took place in early 2020. Phase 2 of restoration work begins in late 2020.
