Pleasantview Road Timber Bridge Completed

February 29, 2012
The completed Timber Bridge!

The West Branch of the Maple in Emmet County is known to support the best trout fishery and coldest water within the watershed. The old crossing (site #E-8) consisted of 3 culverts that were critically failing to the extent that they were blocking fish passage. Erosion from the road shoulders and embankment contributed excessive sand to the river. The undersized and failing culverts caused flooding and consequent warming of upstream waters.

The project involved replacing the existing culverts with a free-span 40ft. timber bridge structure, which will accommodate the natural flow of the river. In addition, the embankments were stabilized, and road runoff is now properly managed to reduce/eliminate sedimentation at the crossing.

Best Management Practices

  • Removal of existing culverts, replaced with 40 ft. timber bridge structure
  • Road and ditch runoff control
  • Pavement and curbing
  • Re-vegetation
  • Stream channel enhancement
  • Streambank stabilization

Project Benefits

  • Estimated 8 tons/yr reduction in sediment loading to the river, benefiting many aquatic and terrestrial species
  • Enhanced unrestricted passage for migratory fish, and access to ~12 upstream miles and ~12 downstream miles
  • Improved safety and appearance
  • Reduced flooding potential and maintenance costs

CRA still has a suite of high priority projects on the Maple River. We'll need the interest and support of many partners to keep improving this beautiful cold-water resource. Contact CRA Biologist, Chris Pierce to find out more and how to help.
