Wisconsin Highway 100
state highway in Milwaukee and Waukesha counties in Wisconsin, United States
State Trunk Highway 100 (STH-100, commonly known as Highway 100 or WIS 100) is a road which encircles the outer edges of Milwaukee County, Wisconsin, United States.
Route description
The road is designed as a bypass around the city of Milwaukee, but with residential and commercial development along WIS 100 on almost all portions of the road, this purpose has been negated, and it serves as one of the Milwaukee area's major commercial corridors. WIS 100 roughly parallels the freight railroad beltway around Milwaukee constructed in 1912 by the Chicago and North Western Transportation Company, approximately one mile inside the north, west and south county lines.
In Milwaukee's immediate western suburb Wauwatosa, WIS 100's north–south segment was once known as Lovers Lane; parts of the road still have this designation. In the vicinity of Mayfair Shopping Center, it is known as Mayfair Road; this corresponds to 108th street in Milwaukee's numbered roadways scheme.
The roadway served the Muirdale Tuberculosis Sanatorium and County Airfield and Limestone Quarry at what is now Currie Park. In the late 1950s, due to the combination of ready roadway and rail access, the area experienced an employment boom as several large cold storage warehouses and food-related truck terminals were constructed nearby. With the development of Mayfair in 1958 by malting scion Kurtis Froedtert, the name was changed to Mayfair Road.
One of the few vestiges of this earlier era is the roadway's popularity as a cruising strip for mainly young motorists showing off their vehicles. West Allis and Milwaukee eventually cooperated to attempt to outlaw cruising on the road as a violation of unlawful assembly statutes, which result in the fining of drivers and impoundment of their vehicles.
This brief starts where responsible research should: with the source description of “Wisconsin Highway 100” as state highway in Milwaukee and Waukesha counties in Wisconsin, United States. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as state highway in Milwaukee and Waukesha counties in Wisconsin, United States. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 9, 2026. The linked authority identifier is Q839298. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1912 and 1958.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
