Construction Impacts

​For I-84 Travelers
  • Periodic nighttime lane closures on I-84 eastbound and westbound throughout the summer.

  • 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 WaNaPa and Frontage Road. 
​More information on construction impacts will be shared in advance of work beginning.

Benefits

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 a new guardrail that meets current safety standards. The bridge will be the same width as it is currently, but 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.
