A major road work project gets underway on Tuesday in Blue Earth County. Highway Department crews will begin construction on Blue Earth County Road 12, from County Road 17 to County Road 3. A bridge will be constructed along with an interchange at Highway 14. The construction will cause lane restrictions and reduced speeds on Highway 14 near Mankato until late fall. This work is part of the final stage of the County Road 12 Extension-Highway 14 Interchange project. It will allow for two miles of arterial roadway, a new interchange and a grade separated crossing of the DM&E Railroad. Motorists are reminded to use caution and watch for workers, traffic control devices and equipment in the work zones.
