About the project

Blue Earth County received funding through MnDOT's Local Partnership Program (LPP) to reconstruct the interchange of Hwy 14 and Blue Earth County Road 57/Riverfront Dr. in Mankato. The interchange was identified as a high priority in the Mankato Area Planning Organization (MAPO) Long Range Transportation Plan, as well as in the Riverfront Drive Corridor Study, citing safety, traffic mobility, and congestion issues. This project is a partnership between MnDOT, Blue Earth County and the City of Mankato, with Blue Earth County serving as the lead agency.
