The Dan Patch Line Bridge is a railroad swing bridge that carries the Canadian Pacific Railway's MN&S Subdivision across the Minnesota River. The MN&S Subdivision is a rail line that originated as the Minneapolis, St. Paul, Rochester and Dubuque Electric Traction Company, more commonly known as the Dan Patch Lines. Today's name for the rail line comes from the Minneapolis, Northfield and Southern Railroad, which took over the Dan Patch route after the original railroad fell into bankruptcy. However, despite being met by Canadian Pacific rails at either end, the bridge itself is owned by the Twin Cities and Western Railroad which has trackage rights on the CP line to the north.
