Minnesota River Flood Mitigation Study

In February 2011, the Minnesota Department of Transportation initiated the Minnesota River Flood
Mitigation Study to investigate lower-cost, shorter-term ways to improve local and regional mobility during
seasonal flooding in the Minnesota River Valley that can force closures of 101 between the Cities of Chanhassen and Shakopee and Highway 41 in the City of Chaska.
