State Trunk Highway 91 (often called Highway 91, STH-91 or WIS 91) is a state highway in the U.S. state of Wisconsin. It runs eastwest in east-central Wisconsin from near Berlin to Oshkosh.

Route description

Starting in WIS49 in Berlin, WIS91 starts to travel eastward, passing Koro. South of Waukau, it intersects WIS116 and CTH-M. Going further east through the Oshkosh city limit, WIS91 intersects and starts to run concurrently with WIS44. However, as soon as they meet I-41/US41 at a diamond interchange, WIS91 ends there. WIS44, on the other hand, continues northeast to downtown Oshkosh.

History

Initially, in 1919, WIS91 was established along part of present-day WIS44. It traveled from WIS23/WIS49 (now just WIS23) in Ripon to WIS15 (now US45) in Oshkosh. In 1924, WIS91 was relocated from the Ripon–Oshkosh route to the Merill–McCord route, causing CTH-E to move just northwest of its former route. This was done in response to the northeastern extension of WIS44. The new route traveled from US51 in Merill to US8 in McCord along present-day WIS107, pre-bypass alignment of WIS10 (after 1926, US51), and present-day CTH-CC. It also functioned as an alternate route of WIS10.

By 1935, WIS91 was removed south of the intersection of US51 (now CTH-A) north of downtown Tomahawk. In 1937, the rest of WIS91 was removed in favor of turning this back to local control (replaced by CTH-CC). This time, the route remained decommissioned for around a year. By 1939, WIS91 was readded right near the location of its second alignment. It traveled from US51 (now CTH-A) north of Tomahawk to US8 in Bradley. In the mid-1980s, WIS91 was decommissioned again in favor of the opening of US51's Tomahawk Bypass and CTH-U. It remained decommissioned until 1996 when WIS91 was readded again, traveling from Berlin to Oshkosh. It superseded a southernmost portion of WIS116 and CTH-X. This time, the new routing still exists to this day.
