100 years of US routes: 1926-2026
US 110 was a short diagonal highway, serving traffic between its "parent" route and US 41. Its northwest end was at its junction with US 10, just east of Fremont. This photo was taken looking north at the former endpoint:
In the 1920s and '30s, US 10 ran both east and west of that intersection. At the time that photo was taken, US 10 was on a newer bypass to the west, but was still using its original route to the east. Now the new US 10 is complete in both directions, and old US 10 east of the intersection is now WI hwy. 96. This photo was looking east on WI 110:
WI 110 turns right there, and ends at its junction with the new US 10. Also the right is westbound WI 96 (which also ends at US 10). Eastbound WI 96 is straight ahead (but was detoured at the time of that photo). That perspective is looking along what was once eastbound US 10, and the beginning of US 110 was to the right.
Ironically, the portion of WI 110 that was formerly US 110 was decommissioned when US 45 was re-routed. So the only remaining portion of WI 110 is the segment that was added after 1960, and only about a mile of that ever served as US 110.
Originally US 110 came into Oshkosh on Algoma Boulevard, ending at its junction with Jackson Street (US 41):
This photo was taken looking southeast on Algoma. Jackson (the cross street) currently carries the US 45 and Business US 41 designations. But at the time of US 110's existence, mainline US 41 ran along Jackson, and US 110 ended here:
However, that arrangement did not last for long. In fact, maps from the very next year showed US 110 turning off Algoma onto New York Avenue...
...and maps from about 1934-1938 showed US 110 using Murdock Street between Algoma and Jackson:
So from 1928-1938, did US 110 end on New York or Murdock, where those roads intersect Jackson? Probably not. Rather, US 110 was likely dual-signed with US 41 down to its original endpoint (Jackson/Algoma), because that is where both the county courthouse and city hall are located.
In 1938 US 110 was re-designated as WI 110. Since then the description of WI 110 has been changed, and it no longer extends to Oshkosh at all.
