Bridge Builders for Wisconsin & Upper Michigan


Working as a private contractor, Radtke builds bridges to satisfy client needs throughout the entire state of Wisconsin and Upper Michigan. In addition to bridges we also construct other types of structures.

We have the ability to perform:

  • Foundational pile driving – Building solid bridge support from the ground up
  • Pre-stressed girder creation and installation – Concrete beams poured and set prior to coming onsite
  • Cast-in-place bridge construction – Concrete poured onsite
  • Box culvert bridge construction – Usually used for smaller bridges over creeks and streams
  • Wooden bridge construction – Typically in the application of walking trails, snowmobile trails, golf courses and general pedestrian bridges
  • Project management  – Of entire process, from permitting through ultimate implementation
