Barron County chose an Aluminum Box Culvert to replace an existing culvert that was not hydraulically
efficient for the current water flow. The structure also gave the county the ability to get a DNR permit
more quickly due to the economical aluminum headwalls and wingwalls being used to support the
shoulder and maintain the natural orientation of the stream.
Since the structure was installed at a 15 degree skew, the headwalls and wingwalls were custom
fabricated to match the center line of the road. The Barron County crew assembled the structure at
an adjacent gravel pit and then used a standard excavator to lift and walk the Aluminum Box Culvert
to the excavated site. This gave them the ability to decrease the road closure time and eliminated the
need for a costly crane generally used for these types of bridge replacements.
