Proposed Views of River Crossing
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
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
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
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.
