magine a regional highway, carrying 15,000 vehicles daily, closed 10 times in 50 years
solely due to flooding. Now imagine five of those closures occurring in the last six years.
Residents of St. Peter and Mankato, MN, USA, along with thousands of Minnesotans
who travel Highway 169 daily, had been dealing with this issue since the 1960s. The

Minnesota Department of Transportation (MnDOT) District 7 and local agencies knew raising
this roadway out of the Minnesota River floodplain was the only solution.
