Jackson County Ditch No. 3 Bridge/Culvert Design

Jackson County, MN | Water

Overview

Utilizing state aid funding, ISG was enlisted by Jackson County Public Works to design five bridge/culvert crossings to replace deteriorated bridges along County Ditch 3 (CD3).

Opportunity

While partnering on a large-scale improvement for Jackson CD3, the County’s public works department noted five aging bridges along the ditch system in need of repair which allowed for projects to be coordinated at the same time, minimizing disturbances for landowners in the area.

Solution

Working with the Watershed’s Drainage Authority on a large-scale improvement project in the CD3 watershed, ISG provided additional expertise by designing five bridges with culvert crossings to meet MnDOT bridge specifications while employing state aid funding. Utilizing a hydrologic and hydraulic model already developed for the ditch system, the water resource team designed five large box culverts to replace the bridges. The culverts met public safety requirements, replaced aging infrastructure, and improved drainage conditions while protecting roadways from flooding.

Key Points
  • MnDOT design specifications
  • Three bridge/culvert designs
  • Flood management
  • Hydrologic and hydraulic modeling
