The bridge was built by Continental Bridge in Alexandria, Minnesota. Continental Bridge prefabricates a wide variety of bridge types and styles for pedestrian use, regional trails, industrial applications, and even small road bridges. The idea is to build the bridge in a factory in a controlled environment where workers have all the right tools, jigs, and materials. The finished bridge is delivered to the side, where it is erected in a single day. The mass customization process allows for a superior bridge to be built at a very competitive price.
This style bridge is called the Connector Truss. It is good for spans of up to 200 feet. Longer spans are built in sections and joined with a field joint. Multiple spans can be joined with support piers to make even longer bridges. The truss can be flat or it can have a slight curve. The truss is formed by a top stringer and a bottom stringer. They are connected by vertical steel members. In addition, one angled brace is installed between each vertical member. There is an option for an X-brace, which results in a stronger truss, but the single brace is more than strong enough for a regional trail. The deck is built on cross members that are set about halfway between the top and bottom of the truss. This allows the top of the truss to be used as a guardrail, and the bottom of the truss has room for cross-bracing.
