Two new spans over the Mississippi River in Winona and La Crosse are among eight North American projects to receive honors from an industry group.
The American Segmental Bridge Institute selected the I-90 and Hwy. 43 bridges as winners of its 2017 excellence awards for projects in the United States, Canada and Mexico.
The 4-year, $189 million project to replace the 49-year-old Dresbach bridge was completed in November 2016.
The selection committee called it a “world-class Mississippi River crossing” and cited innovative approaches to design, materials and rapid construction.” The committee said it combined aesthetically pleasing shapes with two 508-foot concrete spans that are the longest in Minnesota and allowed it to be built with only one pier near the main channel.
The new $78 million Winona bridge was completed in August 2016 adjacent to the existing 75-year-old Hwy. 43 bridge, which is currently being rebuilt and expected to reopen in 2020.
The selection committee commended the bridge’s “graceful haunched superstructure” and “elegant twin wall piers” and called the project “an amazing feat of engineering considering the winter construction.”
The Winona bridge also received a 2017 award from the American Concrete Institute, while the Dresbach bridge was selected as one of the nation’s top 10 projects by “Roads & Bridges.”
