The Wisconsin Department of Transportation says the two, steel truss towers will be placed under the bridge deck on both sides of the pier until it's foundations are permanently fixed.
The towers will cost more than a $1.5 million. Vertical support will also be added to the other piers to ensure the safety of the workers.
"For the piers that haven't settled, we're putting this on as if it were to settle. They would settle vertically, they wouldn't slip to the side or tilt. This would help keep our workers safe." said Kim Rudat of the Wisconsin DOT.
Work is set to begin on Monday and should be completed in early November. However the DOT investigation will continue.
"We're finishing up our investigation, at least the on-sight part." says Rudat, "We'll be working through the weekend and starting next week, we'll be finishing up with soil samples in the Fox River."
A permanent plan for fixing the bridge will be announced in several weeks.
