The Winona Rail Bridge was a swing bridge that spanned the Mississippi River between Winona, Minnesota, and Winona Junction in Buffalo, Buffalo County, Wisconsin. It was built to link the Winona and St. Peter Railroad with The La Crosse, Trempealeau & Prescott Railroad. Both became part of the Chicago and North Western Transportation Company The swing span was removed, but the box girder portion of the bridge still extends from Latsch Island just downstream of the current Main Channel Bridge. Piers from the original 1871 bridge and the box girders are in the North Channel just downstream of the current North Channel Bridge.
