Oregon 38: Scottsburg Bridge Replacement

Construction Phase

Region 3: Southwestern Oregon (Douglas)

​​​​This project will replace the Scottsburg Bridge, providing a wider roadway and adjusting the curves on both ends of the bridge.​​​​


Traffic Impact

Oregon 38: At least one lane of Oregon 38 will remain open at all times during construction. Some single-lane closures will be necessary from time to time, though delays will usually be brief.

Bridge traffic: The old bridge will remain open to traffic until the new bridge is completed.

Local roads: Main Street under Scottsburg Bridge will be closed until spring 2022. Motorists on Scottsburg West Road will be able to use the new spur that connects to Oregon 38 near the north end of the bridge.

Construction cameras

Camera: Scottsburg Bridge work zone

Camera: Oregon 38 in Scottsburg

ODOT has installed two new TripCheck traffic cameras at the Scottsburg Bridge work zone. The first camera looks south at the bridge construction, the other looks east toward Scottsburg.

New photos are taken every 2-3 minutes, but you may have to refresh your browser to see the latest images.


​Overall schedule: This project bid on Nov. 21, 2019. Hamilton Construction was awarded the contract in December 2019. Construction began in February 2020. The new bridge will likely be open to traffic by the spring of 2022. All work, including the removal of the old bridge, is scheduled to be completed by August 31, 2022.

2020 construction: The first year of construction (2020) involved clearing trees and brush, excavating areas along the north and south banks of the river, building work platforms into the river, drilling shafts and building foundations for the new piers, and constructing a retaining wall along the new Scottsburg West Road alignment.

2021 and beyond: During the first half of 2021, Hamilton Construction built the new bridge piers and opened Scottsburg West Road on its new alignment. During the summer of 2021, Hamilton will place more than 25 beams on the new piers. Throughout the fall and winter, construction will continue on the bridge deck and the north approach to the bridge.



This project will replace the 90-year-old Scottsburg Bridge on a nearby alignment, providing a wider roadway and adjusting the curves on both ends of the bridge to better accommodate modern traffic.

What Problem Will This Improve?

​Oregon 38 (Umpqua Highway) is a vital route between Interstate 5, the southern Oregon coast, and the Port of Coos Bay. Although many other bridges along Oregon 38 have been replaced, the Scottsburg Bridge remains largely unchanged since it was built. Opened in 1929, during an era when most vehicles were small and speeds low, the bridge’s narrow lanes and tight corners at both ends are not designed for modern traffic.

What is the solution?

Over the years, ODOT has focused on maintaining the existing bridge and addressing problems as they arise.
Fully repairing the bridge would involve repainting the green steel truss and repairing any bad steel sections, repairing and repaving the deck and replacing the deck joints, replacing the concrete railing, repairing the concrete pier caps, and strengthening the bridge to better withstand earthquakes.
However, such repairs wouldn’t address the more fundamental problems with the bridge—the narrow width, sharp approach curves, and low overhead clearance.

Due to the need for so many repairs and improvements to the existing structure, ODOT concluded that the construction of a new bridge is a better long-term investment. A new bridge will better accommodate modern traffic and will be more likely to withstand a large earthquake or other natural disaster. 
As a result, ODOT is designing a replacement bridge that meets modern standards. The new bridge will be constructed just downstream of the existing structure, allowing the old bridge to carry highway traffic while construction is underway. Due to the cost of maintaining two structures, the old bridge will be removed after the new one is opened.
Construction, including demolition of the old bridge, will continue for three years.​​
