Stahly Engineering assisted Fergus County in securing TSEP funds for the replacement of the bridge. Additional services provided by Stahly Engineering include:

Survey and construction staking

Road design and plan development
Construction administration, including TSEP grant administration
Construction inspection

This bridge is located over Big Spring Creek, and is in a detailed flood study area, meaning the water surface of the creek could not be increased at all. In addition, lengthening the bridge to accommodate hydraulics was a challenge due to the proximity to the highway on the east, and a residential driveway on the west.
