Goodpasture Covered Bridge crosses the McKenzie River near Vida, about 20 miles east of Springfield. The bridge provides sole access for more than 80 residences and a large area of forest lands.
This project will construct a seismic retrofit of the bridge to improve its resilience to earthquakes, such as a Cascadia Subduction Zone event. Retrofit elements are expected to include installing rock anchors at the west (highway) end of the bridge, and removing weak soil at the east end.
The structure is timber and therefore at higher risk from fire. The 2020 Holiday Farm Fire came very close to the bridge, which was saved by fire suppression efforts. This project is expected to include fire mitigation measures, such as sprinklers or fire-resistant materials.
