The County HH bridge over the Wisconsin River in Whiting, WI, was chosen as a Stevens Point bypass route.
The bridge location, however, posed a number of challenges. It was not possible to use a single span bridge. East and west bound lanes needed to be on separate bridges because of topography differences over the landscape on both sides of the river and on an intervening island. The island could serve as a midpoint to bridge spans, but the island and the river channels around the island were known nesting locations for a state threatened bird and rare fishes and clams.
AES conducted detailed surveys and mapping of terrestrial and aquatic natural resources, endangered resources and regulatory wetlands. With survey information, ecologists created solutions to avoid nest locations, wetlands, and mollusk beds. The scientific design process also illustrated ways to avoid placing the bridge, and the shadow cast by the bridge, over important spawning areas for Sturgeon and other special status fish in the river channels surrounding the island.
AES prepared the environmental and ecological contributions to the EA documentation. Ecologists contributed extensively to the public process with neighboring community stakeholders, community agencies and other team members by providing scientific underpinning to inform public concerns.
Ecologists conducted field meetings with federal and state regulators and negotiated resolutions to issues that assisted in obtaining the permitting for the preferred alignment of the bridge and approach roads.
