SCOTTSBURG — Work is underway on the Scottsburg Bridge replacement on Oregon Highway 38. 

The project will replace the 90-year-old bridge over the Umpqua River in Scottsburg, providing a wider roadway and adjusting the curves on both ends of the bridge to better accommodate modern traffic.

At least one lane of Highway 38 (Umpqua Highway) 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.

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

A 200-foot section of Scottsburg West Road is closed near the north end of the bridge for realignment work. The closure will continue until the spring of 2022. Motorists on Scottsburg West Road are advised to drive under the bridge and use Main Street to reach Highway 38.

The project bid on Nov. 21, 2019. Hamilton Construction of Springfield 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 Aug. 31, 2022.

From February to April, 2020, Hamilton Construction set up road signs, cleared trees and brush, built access roads, demolished a condemned house in the work zone and lowered the Main Street road surface under the bridge to increase vertical clearance.

From now until summer, Hamilton Construction will build a retaining wall along Scottsburg West Road. During the summer, Hamilton will construct a work platform that extends into the Umpqua River.

​Background

Oregon 38 (Umpqua Highway) is a vital route between Interstate 5, the southern Oregon coast and the International 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.​​
