Why this project is needed
 Although traffic volumes are low on OR 206 and over the bridge, it is an important highway for accessing the Deschutes River and an alternative route if Interstate 84 is closed. Keeping highways in good condition and providing a safe, efficient transportation system that supports economic opportunity are critical parts of the mission for the Oregon Department of Transportation (ODOT).
The Deschutes River Bridge #00332 was built in 1955 and is approximately 650 feet long and 35 feet wide. Currently, the bridge is load limited due to concerns about the girders (superstructure) supporting the roadway. There is concern that if a significant earthquake occurred, the bridge would sustain major damage. The approach, transition and bridge railings are all substandard and needs to be replaced or modified. And there are some bridge deck joints that are in need of repair.
What is planned
The current plans are to:
- Strengthen the superstructure so the current load limit can be lifted, and allow most interstate vehicles to cross the bridge if I-84 is closed,
- Replace the approach and transition railing at either end of the bridge, and upgrade the railings on the bridge,
- Repair the deck joints as needed, and
- Complete a seismic upgrade of the bridge.
Traffic control during construction
During construction, traffic on the bridge will be limited at times to one travel lane. Traffic will be controlled by flaggers or a traffic signal system.
