Wildcat-Wallupa Bridge Replacements

  • GRMW ID: 1823
  • Fiscal Year: 2008

The project proposes to replace two undersized, failure-prone culverts on Wildcat Creek and Wallupa Creek with channel-spanning bridges. Both structures have failed multiple times, each time introducing large quantities of road fill, surface gravel and soil into the Wallupa Creek, Wildcat Creek and the Grande Ronde River. The existing structure on Wildcat Creek is a partially crushed, undersized bottomless arch that at times presents a velocity barrier to adult steelhead. The structure on Wallupa Creek is an 8-foot round culvert that blocks all upstream passage of adult and juvenile steelhead and resident fish. The replacement bridges meet all fish passage criteria and are designed to pass 500 year flows without failure.
