U.S. 30 Troutdale Bridge

Design Phase

Region 1: Portland metro and Hood River County (Multnomah)

​​​​​​​We are designing a project to extend the safety and lifespan of the Troutdale Bridge over the Sandy River. This project will add scour protection to the bridge piers which will reduce the potential for water to deteriorate the bridge supports. ​

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


Construction Impacts

There will be some limited traffic impacts on the bridge during initial setup of the construction site. Most of the work will be conducted over/near the water, and we do not anticipate any impacts to traffic on the bridge deck or nearby roads during construction. 

This portion of the Sandy River is popular with recreational users and the project may direct river users into a smaller section of the river or potentially restrict river access for several hours during construction. These safety measures are critical to protect river users during construction.

Additional information on impacts and schedule will be shared as construction approaches. Plan ahead by signing up for project emails to stay informed.


​Construction is anticipated to begin in 2024. Schedule is subject to change. 



​The Troutdale Bridge over the Sandy River is a historic bridge on the Historic Columbia River Highway. The bridge was constructed in 1912 and needs repairs to extend its lifespan. Over time, flowing water can remove sediment around a bridge’s support structure, in a process called bridge scour. This project will add scour protection in the water around the bridge piers to reduce the potential for water to deteriorate the bridge supports.
