Oneonta Tunnel Rehabilitation project wins ACEC Oregon’s 2022 Grand Award! The 2017 Eagle Creek Fire substantially damaged the Oneonta Tunnel, creating unsafe conditions and forcing a closure. DEA and project partner GRI provided design services to rehabilitate the existing tunnel and mitigate hazardous rockfall from the fire-damaged bluff. The team’s services ultimately contributed to reopening this recreational facility for users to experience the beautiful Columbia River Gorge National Scenic Area.
DEA is proud to be part of this project resulting from the extraordinary vision of the Oregon Department of Transportation and Western Federal Lands Highway Division.
