The Minnesota Department of Transportation hired Michael Baker’s Minneapolis team to serve as the final design Engineer of Record, taking on the challenge of extending the Winona Bridge’s service life another 50 years, preserving the historical integrity of this 75-year-old bridge and satisfying the requirements of Chapter 152 state law.
The rehabilitation of the Winona Bridge represented the most complex historic truss bridge rehabilitation ever undertaken by the Minnesota Department of Transportation (MnDOT). To extend the bridge’s life another 50 years, the team performed an extensive bridge analysis, evaluation and rehabilitation that preserved the historical integrity of the 75-year-old structure. The bridge was honored as the Merit Award Winner in the Steel Bridge Rehabilitation category.
To date, the Winona Bridge project has received the following recognition:
- 2019 ACEC Minnesota Engineering Excellence Grand Award
- 2019 ACEC National Recognition Award
- 2019 Prize Bridge Award from the American Institute of Steel Construction (AISC) and National Steel Bridge Alliance (NSBA)
