| Abstract: |
The new St Croix River Bridge in Minnesota is a critical new piece of infrastructure required to replace the existing functionally obsolete Stillwater Lift Bridge which was constructed in 1931. The form of the bridge was developed over a long exhaustive process required to address stakeholder issues with the environmentally sensitive site. The paper describes the process for the development of the project, including the basis for the selection of the extradosed bridge form, and the aesthetic theme and features developed and incorporated into the design to address the stakeholder concerns. |
