South Fork Wilson River Bridge

LC Eco often works with the Oregon Department of Forestry, completing construction ready design sets for culvert and bridge replacements as they improve state forest infrastructure. This often includes fish barrier removals and enhancing habitat quality for multiple fish species. For this project we provided engineering services for the replacement of the South Fork Wilson River 0.5-mile Bridge.
