In 2005 the St. Croix Visual Quality Review Committee (VQRC) and Project Team (Wisconsin DOT, Minnesota DOT and Consultant Team) enthusiastically chose the "Organic" architectural bridge concept for further development. This concept successfully balances engineering and functional criteria of cost, maintenance and construction means with visual, aesthetic and architectural project criteria. Of the three concepts presented at the mid-September Open Houses, the public also preferred this concept. Working with the VQRC, the Project Team will continue to move forward with further architectural and engineering refinement of the "Organic" concept.


St Croix River Bridge Proposed Visual Design Concepts

A Visual Quality Review Committee identified three concepts for further refinement and comparison for the river bridge. All bridge design options that are being considered are consistent with the DOT’s commitment to build an “extradosed” bridge. Extradosed bridges have relatively short towers above the bridge with cables extending from the tower to the bridge surface. There is no difference between the concepts with regard to the number of piers in the water or location of the bridge surface. The descriptive names of HULL, ORGANIC, and PORTAL have been assigned to help identify each option.

HULL - A dynamic design to create a welcoming feel with open arms that are inspired by the timber and boat industries.
ORGANIC - A simple design that is meant to imitate a reed-like growth out of the river and act as thought it has been shaped by natural forces.
PORTAL - A tube design that encloses bridge users and has a smooth form that expresses movement across the valley. The following photo simulations are shown from six viewing areas for each of the three concepts plus the existing setting.

Revised bridge concepts presented to the VQRC October 5th to address further structural review. Visuals show a deepened bridge deck on each concept. The Organic Concept has had an additional column added to each support and the Hull concept's pier has been divided.
