It took me several hours and numerous references in Google and here, but the route description of this highway is complete. jwhouk 12:16, 2 March 2012 (UTC) — Preceding unsigned comment added by Jwhouk (talk • contribs)

The author has confused the shores of the Black River/Lake Onalaska with the Mississippi River. The Black River does not suddenly disappear around Lake Onalaska and then reappear near the spillway. The "eastern shore" of the Mississippi River has never come close to the corporate boundaries of the City of Onalaska, Wisconsin. The flow of the historic Black River in Onalaska still exists, despite the reservoir known as Lake Onalaska. To the best of my recollection, the geographic term "Mississippi River" does not even appear in the index in the 1985 local history book about Onalaska, "From Sawmills to Sunfish." The Mississippi River is not associated with the history of the townsite, village or city of Onalaska. The Black River empties into the Mississippi River near or at Riverside Park in the City of La Crosse. Unlike Winona, Minnesota, Onalaska never had any lumber mills on the Mississippi River. Both Onalaska and north La Crosse had lumber mills on the Black River. — Preceding unsigned comment added by 2600:6C44:437F:EA8B:6494:440E:C4CE:7DA5 (talk) 21:15, 26 February 2021 (UTC)Reply
