May 2014 newsletter

  • Bridges on US 12 over WIS 50 will be replaced
  • The new bridge over US 41 will meet the vertical clearance of 16 feet by nine inches
  • A multi-use trail will be added to WIS 50 under the bridge
  • Realign intersection ramp terminals to improve and meet design standards


The current condition of the roadway and bridge is highly deteriorated. The additional bridge height will help support industry by allowing the shipment of oversized loads. The multi-use path will allow the local community the ability to extend their trails offering a new crossing under US 12.
