Preferred alternate selected for Winona Bridge spans rehabilitation

WINONA, Minn. – The Minnesota Department of Transportation and its partners have chosen a preferred alternate in the rehabilitation of the existing through-truss bridge in Winona that lengthens the approach spans in the city and uses modern concrete beams, while still providing a structurally sound crossing and maintaining its eligibility for the National Register of Historic Places.

The decision, reached in consultation with MnDOT, the Federal Highway Administration, and the Minnesota Historical Society, will modernize spans #1-#15 in Winona in a non-historical manner by lengthening the spans and utilizing modern concrete beams, closely matching the spans of new Bridge No. 85851.  In addition, the existing six deck truss spans #16, #17 and #21 through #24 will be replaced by replicating their historical character.

“We feel this is a good decision reached through collaboration, discussions and analysis with all of our project partners,” said Terry Ward, MnDOT project manager for the Winona Bridge Project. “We received numerous comments of support from the Winona community on this alternate.”

The proposed Work Package #6 details represent a change from the improvements described in the 2013 Environmental Assessment. Therefore, the preferred alternate is being re-evaluated to identify any resulting changes in social or environmental impacts. The re-evaluation process will conclude with a decision that either the 2014 “Finding of No Significant Impact” remains valid or that additional environmental documentation and clearance is needed.

The cost estimate for the Work Package #6 preferred alternate is $27-$29 million, approximately $2-$2.5 million less than the full historical rebuild MnDOT was originally planning for the Work Package #6 scope of work.  The current letting date is May 24, 2017,

In March 2016, Ward announced that the project was estimated to be $30 million over budget and that MnDOT and its partners are hitting the “pause button.” The overall project cost overrun came into sharp focus based on the results of a 90 percent cost estimating phase for Work Package #5, which was the rehabilitation of the existing bridge.  This estimate was the first time MnDOT had obtained actual price quotes from subcontractors and suppliers. MnDOT was able to split the work packages into two parts to continue the project into the rehabilitation phase. It opened the new bridge in Winona on Aug. 27, 2016, ahead of schedule.

The use of the Construction Manager General Contractor procurement method for Winona Bridge Project has allowed cost estimating as the project progresses in work packages allowing for the opportunity to trim costs, if viable and safe.
