(Mankato, MN) The Minnesota Department of Transportation, along with the city of Henderson, Sibley County, Scott County and Le Sueur County, has initiated a feasibility study to investigate transportation improvements in the Minnesota River Valley during flood events.
The goal of the study is to identify safe and accessible routes to and from Henderson and to limit the length of detours and impacts to businesses and regional traffic during high water events. The focus of the study is on the bridges and approach roadways for Highways 19 and 93 and Sibley County Road 6.
“Henderson has been hit hard in recent years with closures due to flooding, during these flooding events and the impending cleanup, three of the four major routes into Henderson are frequently closed to traffic” explains Matt Young, MnDOT project manager. Road closures have been at an all-time high in recent years.”
More specific tasks of the study include a benefit/cost analysis of elevating roadway profiles (Highway 93 and County Road 6), raising bridge and roadway approaches (Highway 19) and improving roadway stability to mitigate slope failures.
Techniques that will be used include developing hydraulic models, modeling traffic and designing alternatives.
The feasibility study should be complete by December and includes involving the public. The first newsletter has been posted on the website at www.dot.state.mn.us/d7/projects/hwy19study/ and the first open house will be held in the spring.
