MANKATO — Flooding in and around Mankato has closed some city streets and area highways.

Seven inches of rain late Tuesday and early Wednesday overwhelmed the city’s storm sewer system. About a dozen streets, including Riverfront Drive, are closed due to flooding. Public works crews are busy clearing debris from city street.

Meanwhile, the Minnesota Department of Transportation says Highway 66 is also closed south of Mankato from Highway 169 to Blue Earth County Road 9 because of a mudslide. Highway 169 southbound between St. Peter and Mankato closed earlier because of flooding has been opened.
