History

State Highway 105 was authorized on April 22, 1933. The route was paved by 1940. From 1934 to 1980, the northern terminus of Highway 105 was previously at old U.S. 16 / old Minnesota 116 (Oakland Avenue) in Austin. Minnesota 116 was turned back to city maintenance in 1980. The 1.6 mile connecting route of old Minnesota 116 (Oakland Avenue) between Highway 105 at 12th Street and Interstate 90 on the western side of Austin was then added as an extension of 105 in 1980. Highway 105 is currently a turnback candidate because of low traffic volume and it ends at a county road.
