Project summary

  • The bridge over the Cottonwood River south of Sanborn was replaced.
  • The previous bridge was built in 1931 and was near the end of its useful life.
  • The new bridge is wider with 12-foot driving lanes and 10-foot shoulders.
  • Minor work took place on the approaches to improve drainage on the bridge, including reshaping the ditches and stream stabilization.
  • New guardrail was installed.
  • Two gravel passageways were installed under the bridge on both sides of the river to encourage wildlife to follow them instead of crossing on the roadway.
