Work on foundation piers begins in spring
ST. PAUL, Minn. – The Minnesota and Wisconsin departments of Transportation announced late last week that they will accelerate the St. Croix Bridge project by starting construction on bridge foundation river piers in 2013.
“We have been working on integrating the results of the load testing to make the project more efficient in terms of managing scope, schedule and budget,” said Jon Chiglo, MnDOT project director. “By separating out the foundation work, we can start construction sooner, reduce inflation costs and create jobs a year earlier than scheduled.”
The $50 million contract will open for bids in late winter 2013. Construction is anticipated to begin on the bridge foundations in late spring next year. Previously, construction was planned to begin in spring 2014.
The St. Croix Crossing project replaces the 80-year-old Stillwater Lift Bridge with a four-lane bridge connecting highways on both sides of the St. Croix River in Stillwater and Oak Park Heights, Minn. and St. Joseph, Wis.
The also project adds extensive trail systems, including converting the Lift Bridge to a bicycle and pedestrian crossing. It also includes constructing three miles of four-lane highway on Wisconsin Highway 35 and reconstructing about three miles of Minnesota highways 36 in Oak Park Heights and 95 in Oak Park Heights and Bayport.
The new St. Croix Crossing Bridge is estimated to cost between $280 million and $310 million. The total cost for the entire St. Croix Crossing project is estimated at between $580 million and $676 million.
