OMNNI provided design and plans for more than 30 steel sign support structures for the Wisconsin DOT on highways in the counties of Winnebago, Fond du Lac, Outagamie and Douglas. Structure types included cantilevers, butterflies and bridges. These sign support structures were designed to meet AASHTO and WisDOT requirements.
Structural design included:
• Galvanized steel structural members with primarily welded connections
• Coupling plates designed for each bridge structure
• Coordination with OMNNI’s transportation engineers for design of foundations and anchorage to concrete bridge structure
