Wisconsin Highway 123
# Wisconsin Highway 123

State Trunk Highway 123 (often called Highway 123, STH-123 or WIS 123) is a former short state highway in the U.S. state of Wisconsin. It ran north–south in south central Wisconsin from the entrance to Devil's Lake State Park to Baraboo. It was phased out in June 2016 and turned over to local jurisdictions and County DL was extended.

## Route description

Starting at the entrance of Devil's Lake State Park, WIS 123 briefly traveled northeastward. Then, after it began to travel northward, it intersected WIS 159 (now WIS 136). It continued to travel northward towards downtown Baraboo via present-day CTH-DL, Walnut Street, and Parkway. Then, it began to run concurrently with Bus. US 12 for the rest of the route. After that, they ran along South Boulevard for a short distance. After crossing above the Baraboo River, they began to run concurrently with WIS 113. The three then continued north as Broadway before all but Bus. US 12 ended at WIS 33.

## History

In 1919, WIS 123 was established to travel from Devil's Lake State Park to WIS 12 (now Bus. US 12) in Baraboo. In 1936, WIS 123 was extended north to WIS 33 via a former portion of US 12. This was done in response to US 12 being moved westward onto a 1936-era bypass.

Up until 2016, no significant changes had occurred. Then, in April 2016, WIS 123 began to be in the process of refurbishment. The route was later decommissioned in June 2016 as part of the project. Today, the former route outside of Baraboo was then superseded by CTH-DL.

## Major intersections

The entire route is in Sauk County.
