I-84 Forest Lane Bridge

Project Completed

Region 1: Portland metro and Hood River County (Cascade Locks, Hood River)

​Construction is complete for this project. ​​​​​In 2022, we raised the Forest Lane bridge over I-84 in Cascade Locks to accommodate tall and/or over-height trucks.​

Cost and Funding

​Project cost: $4.4 million


​​HP Civil


Before construction, the bridge was the last low-height structure between Troutdale and Hood River on this critical freight route. Raising the existing 16.7-foot structure to 17.4 feet has allowed tall trucks to use I-84 instead of using alternate routes.

Additional Information

Frequently asked questions

What were the benefits?
Using alternate routes, like Oregon 35 and U.S. 26, due to height restrictions on I-84 can be costly and time consuming. Using I-84 saves businesses time and money and improves safety on roads used as alternate routes. 

Did ODOT consider lowering I-84 instead of raising Forest Lane?
Yes, we found raising the bridge height to be the most cost effective option while minimizing impacts to the environment and I-84 traffic. 

Did you make any improvements to the bridge?
The bridge was raised to the new height and a new guardrail was installed that meets current safety standards. The raised bridge is the same width as it was before construction, but has been striped to show shoulders. 

Columbia Gorge Projects

Over the next several years, we have many construction projects planned on I-84 between I-205 and Hood River, and on the Historic Columbia River Highway between Troutdale and Hood River.
