Minnesota River Valley flooding has created maintenance and travel challenges for the local community and MnDOT for decades. After completing a Flood Feasibility Study in 2017 and securing state funding in 2020, Hwy 93 will be raised approximately eight feet, putting it one foot above historic high-water events.
Additionally, the lowest point of Hwy 19 (east of Henderson) will need to be extended to offset impacts to the floodway when Hwy 93 is raised. This Hwy 19 work between the Minnesota River Bridge and railroad bridge will take place in 2022, in advance of Hwy 93 construction starting in 2024.
Sibley County also received flood mitigation funding for CR 6. Between 2022 and 2025, CR 6, Hwy 19, and Hwy 93 will all have improvements related to flood mitigation.
