This project included the removal of an aging 10’ diameter steel culvert over Erick Creek on Abernathy Creek Road and replacing it with a Multi Plate Steel Arch Culvert with cast in place stemwalls, wingwalls and headwalls. Other critical elements of the project included installation of a stream bypass , restoration of the original streambed and removal of invasive vegetative species. The project also included the use of an automated 1-way directional traffic signal to route traffic around the construction site. This improvement will allow fish passage from the Columbia River, up Abernathy Creek and then into Erick Creek.
