I-84: Forest Lane Bridge Raising

Construction Phase

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

​​​​​​In Cascade Locks, ODOT is raising the Forest Lane bridge over Interstate 84 to accommodate tall or over-height trucks.

Columbia River Gorge Construction: I-84 and U.S. 30 Historic Columbia River Highway


Construction Impacts

For I-84 Travelers 

During construction, I-84 under the bridge will be reduced to one lane in each direction around-the-clock to provide space for work to occur. The shoulder will be narrowed during construction. People cycling can use the narrowed shoulder or detour through Cascade Locks. 

 For Forest Lane Travelers 

During construction, Forest Lane will be closed around-the-clock at the bridge to all users. Local access for businesses on the northwest side of the bridge will be open. People driving, walking or biking can follow a signed detour on Wa Na Pa and Frontage Road. 

 More information on construction impacts will be shared in advance of work beginning.

Nighttime Noise

Those living or working in the area may hear noise from construction. A 24/7 nighttime noise hotline is available for noise concerns: 503-294-1570.


  • ​Design complete in 2021. 
  • Construction is planned to occur February through summer 2022.​
Schedule is subject to change.

Cost and Funding

​Project cost: $4,376,366.00​


The bridge is 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 will allow tall trucks to use I-84 instead of using alternate routes.

Additional Information

Frequently asked questions

What are 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. It also 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. 

Are you making any improvements to the bridge?
The existing bridge will be raised to the new height and we will install new guardrail that meets current safety standards. The bridge will be the same width as it is currently, but striped to show shoulders.

Nearby projects

The Columbia River Gorge is one of Oregon’s seven wonders – home to the first highway in the Pacific Northwest, sweeping vistas and rich history. And for more than 100 years, it’s been an important corridor for freight movements, both in the water and on the road.

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

Each project brings benefits to residents, businesses and visitors by increasing safety, extending the lifespan of the highways or completing a gap in walking and biking infrastructure.
