Minnesota Junction was founded when the railroad was built to that point. The community was so named from the expectation the new railroad line would eventually extend from Minnesota Junction to the Minnesota Territory. A post office was established in Minnesota Junction in 1861, and remained in operation until it was discontinued in 1940. The junction was situation where a northâÂÂsouth branch of the Chicago and North Western Railway met an eastâÂÂwest branch of the Milwaukee Road. The northâÂÂsouth line was abandoned in 1984, and is now a rail trail, while the eastâÂÂwest line is still operated by the Wisconsin and Southern Railroad.
