Construction milestone: final Winona Bridge concrete segment pour completed
WINONA, Minn. – A major construction milestone on the new Winona Bridge was completed on Friday, March 25 when crews completed the final bridge segment concrete pour for the 50th cast-in-place section on the main Mississippi River channel crossing, said the Minnesota Department of Transportation.
“Our thanks goes out to Ames Construction and the MnDOT oversight team and all the construction workers who’ve made a tremendous commitment to meet this critical milestone,” said Terry Ward, MnDOT project manager for the Winona Bridge. “They’ve worked in extreme winter conditions and given up numerous holidays to provide a high quality structure in a safe environment on an extremely aggressive delivery schedule.”
The final pour of the segment was completed at noon on Friday, said Eric Breitsprecher, engineering specialist with MnDOT. The bridge slab and segmental box concrete includes 106,801 square feet of space and 4,311 cubic yards of structural concrete. There are also more than 500,000 pounds of post tensioning strands, more than 2 million pounds of rebar, and 2.7 million pounds of steel.
Ward noted that people will still see gaps between the poured segments. Closures pours will be done to complete those gaps, along with grouting. Later, railings will include 2,355 linear feet of ornamental railing and 6,930 feet of concrete railing.
The bridge interior area will eventually house a time capsule. MnDOT has granted permission to the Winona County Historical Society, along with student coordinator Bailey Bestul of Winona, to coordinate the collection of Winona-area items of interest to future generations.
The completion of the new bridge is on target to be opened by the end of 2016. Extensive photo documentation is available at the kiosk at the Winona County History Center and the Facebook page photo albums at www.facebook.com/WinonaBridge.
