OR 38: Elk Creek to Hardscrabble Creek

This $47 MM design build multi-discipline highway project consisted of the design and replacement of five bridges over environmentally sensitive waterways in multiple work zones along OR 38. The project also included upgrades to the OR 38/OR 138 intersection. The project stretched over a 14-mile section of OR 38 between the cities of Drain and Elkton, Oregon.

The project included extensive in-water work, including six cofferdams to facilitate the demolition of the old bridges and to construct the new bridge piers. All of the in-water work had to be completed during the July 1 to September 30 in-water work period.

As the design-builder, Slayden was also responsible for obtaining all permits and clearances for the five bridge sites. Elk Creek contained Coho Salmon, a listed species under the endangered species act. The project also contained critical habitat for the Northern Spotted Owl, another listed species.

Two of the five bridges were replaced using a “Rapid Replacement” technique, in which the new structure is built adjacent to the existing structure, then “slid” into place after removal of the existing structure. The two rapid replacements were each completed during a 48-hour weekend closure.

Total Project Value: $47.1 million

Management Skills that Help Reduce Costs

"We have been impressed with their management skills, starting with preconstruction where they performed value engineering that reduced costs, lead procurement with detailed bid packages that brought our project qualified subcontractors and manufacturers and produced a schedule that would get our project completed on time. Slayden has continued this into the construction phase by managing the work to stay on schedule."

Randy Rosane, P.E., Project Manager with Water Environmental Services

"Slayden’s positive approach and eagerness to achieve the project goals was a tremendous benefit and a driving force to the project and its success.

This has led to the development of relationships between the project team and the neighborhood, which have contributed to the project in a positive manner."
