STH-175 “Old Highway 41 from the Brewers Ballpark to the ‘Bottom’ of Lake Winnebago”


Sample towns along the way: Milwaukee, Menomonee Falls, Richfield, Slinger, Addison, Theresa, Lomira, Fond du Lac

Bypass alternates at: You can use I-41 to bypass any town or section of Highway 175, since they parallel each other most of the way.

WisMap175Quickie Summary: State “Trunk” Highway 175 basically is what U.S. Highway 41 was before the 4-lane expressway version opened between northwest Milwaukee and Oshkosh in the mid-1950’s. So basically, every town that U.S. 41 (now Interstate 41) now skims past, Highway 175 goes through the heart of. It’s an interesting study in how towns change when the main road is relocated; some spiffed up their main streets, some seemingly relocated everything toward the new highway. But if you’ve never really seen places like Lomira or Slinger or the downtowns of Menomonee Falls and Fond du Lac, take 175 instead of 41 and check ‘em out! They even used Highway 175 to replace U.S. 41 in Milwaukee when they re-routed it to the Interstate, furthering the route’s identity as “Old 41.”

The Podcast

We talk about Highway 175 in this State Trunk Tour podcast, providing an overview:

Wisconsin Highway 175 Road Trip

The Drive (South to North): Highway 175 now begins at Highway 59/National Avenue in West Milwaukee within full view of American Family Field, home to the Milwaukee Brewers.

Highway 175 beginning as you approach Highway 59 in West Milwaukee
Heading north on Miller Park Way in West Milwaukee, you approach the beginning of Highway 175 at National Avenue, which is also Highway 59. In this photo, you see the first 175 marker, and Miller Park is visible in the distance.


Once Highway 175 begins, you’re on a rebuild of what was Milwaukee’s first expressway segment. Originally called the North 44th Street Expressway and then the Stadium Freeway, this segment opened in 1962 to serve Milwaukee County Stadium and connect with the newly-built (at the time) I-94. Where this freeway segment and I-94 cross was the first freeway-to-freeway interchange completed in Milwaukee, and is slated for a rebuild in the next few years. This stretch was designated U.S. 41 from 1962 to 1999, and then Highway 341 temporarily before the Highway 175 designation by 2015. South of I-94, this segment was reconstructed in 1999 to coincide with the opening – and new footprint – of American Family Field (aka, “AmFam”.) From I-94 on north, it’s pretty much the original 6-lane freeway from the early 1960s for a few miles. Highway 175 meets with U.S. 18/Bluemound Road and then leapfrogs the Menomonee River Valley (home to the Miller Brewery) into the north side of Milwaukee.

Highway 175 begins at the Stadium Interchange in Milwaukee from I-94, where the other option is Miller Park Way (now called “Brewers Blvd.”)- the ballpark is RIGHT there.
Heading south on 175, formerly U.S. 41, American Family Field dominates the view at the end. Highway 341 begins here and continues south for barely a mile for some reason.


The Valley – Miller & Harley

Highway 175/former U.S. 41 is a key connection to the Miller Brewery, via the exit at State/Vliet Streets. Once home to Miller Brewing Company’s world headquarters – now in Chicago after the MillerCoors merger – they still brew over 45 million barrels of beer in “Miller Valley” each year, from Miller Lite and High Life to specialty brews and even old-school brands by contract, including Schlitz, Pabst, Old Style, Blatz, and more. Tours of the brewery and plant are incredibly popular and run every half hour from 10am-3:30pm most Mondays-Saturdays. You can call (414) 931-BEER to check on schedules of these tours, which are free and include three complimentary beers. Off the highway a bit but literally across Highland Boulevard from Miller’s regional offices lies the Harley-Davidson Motor Company headquarters. This sprawling complex is the heart of Harley’s leadership and operations and for bikers, a picture out front with the Harley sign is often a must. The engine and bike manufacturing takes place elsewhere, but for the plans, promotions, and other things tied to these classic bikes and the Harley lifestyle, this locale at 38th & Highland is the “mother ship.” Further west along State Street just into suburban Wauwatosa, a newer microbrewery called Big Head Brewing offers craft brews, so you can enjoy a huge brewery and a tiny craft brewery in close proximity via the State Street exit.

Back to Highway 175, the freeway winds over State and under Vliet Streets and past Washington Park, a beautiful urban park that once held the city’s main zoo. The freeway ends there, once intended for continuation but stopped during the “freeway revolt” years during the late 1960s and early 1970s. At this point, traffic moves to ramps and then is routed onto Lisbon Avenue, which runs northwest and was U.S. 41 originally when the route was first designated in 1926.

This freeway stretch has remained largely unchanged since 1962, except for U.S. 41 becoming Highway 175 in 2015.

Highway 175 meets up with the Zoo Freeway, which was solely U.S. 45 for fifty years before also picking up the I-41 & U.S. 41 designations in 2015. This unusual interchange consists of sweeping ramps that allow access to northbound I-41 only when heading northwest, and southbound I-41/U.S. 45 only when heading southwest. The interchange has been configured this way since its construction in the 1950s, when Appleton Avenue was a bigger deal than U.S. 45. That’s definitely different now.

Highway 175 approaching I-41/U.S. 45, which is an unusual interchange on the border of Milwaukee and Menomonee Falls.

Within blocks of the interchange, you leave Milwaukee to enter Waukesha County and Menomonee Falls (pop. 35,626), Wisconsin’s largest “village” (they haven’t gotten around to applying for city status yet.) Menomonee Falls occupies the northeastern corner of Waukesha County and serves as corporate headquarters for the Kohl’s Corporation, Cousins Subs, Alto-Shaam, and even Strong Funds before Eliot Spitzer got his hands on them.

As Appleton Avenue, Highway 175 continues as a six-lane boulevard heading into the downtown area, but tapers to a smaller street and enters the heart of downtown, referred to as the “Historic Village Centre”. The downtown crossroads intersects with Main Street – formerly Highway 74 – and passes a variety of craft stores, boutiques, salons and restaurants.

After Menomonee Falls and the rapid growth along County Line Road (where you enter Washington County), Highway 175 becomes more of a rural-type two-lane road and begins to string together a series of towns as the road to Fond du Lac begins, making for a nice drive in the country. I-41/U.S. 45 parallel about mile to the northeast here.

Part of that nice drive in the country includes scenic views, like from atop Meeker Hill (pictured below). Remember, this used to be U.S. 41 and all that through traffic must have had a tough time chugging through here, especially when people would travel up north for the weekend.


Atop Meeker Hill, featuring a view topping 15-20 miles. As you can see, the view varies based on whether it’s June or January.

Highway 175 provides good access to the twin steeples of Holy Hill, by either heading west at the Highway 167 crossing in Richfield or south on Highway 164, accessed by a ramp after an underpass at Ackerville.

Near Ackerville and the underpass under Highway 164, Highway 175 has a bar that names itself partially after it – Sheryl’s Club 175. As you know, it’s State Trunk Tour policy to salute establishments that name themselves with their highways.
Today’s Highway 175 dealt with busy traffic prior to 1953, when this stretch was part of U.S. 41 and the Yellowstone Trail. Old gas station sights like this are common. And somehow fascinating, since they capture a different time and have changed little since.



Many may not know where downtown Slinger (pop. 4,109) is, but Highway 175 cuts right through it just north of Highway 60. Cool older buildings like St. Peter’s church show architecture from the time Slinger (originally called “Schleisingerville” fer cryin’ out loud) was an outpost village perched at the edge of Kettle Moraine. As a matter of fact, the downtown intersection leads to the start of Highway 144, part of the Kettle Moraine Scenic Drive, at I-41 just to the north.

Several points of interest lie on the other side, including Held’s, a great place to stock up on Sconnie eats like cheese and beef jerky, Little Switzerland Ski Area, featuring 15 runs and 5 chair lifts; and Slinger Super Speedway, known as the World’s Fastest Quarter Mile Oval.

Slinger Super Speedway has been around in one form or another since 1948 and was paved in 1973. A paved “X” infield allows for Figure 8 racing, and the quarter-mile oval hosts races for stock cars and modifieds of almost all types. Drivers like Matt Kenseth, Dick Trickle, Alan Kulwicki, Mark Martin, Dale Earnhardt, Kyle Petty, Ernie Irvan, Sterling Marlin, Ted Musgrave, Rusty Wallace and, well, the list goes on and on.

State Trunk Tour Tidbit:
Little Switzerland Ski Area, named after a neutral nation, opened on December 7, 1941, the same day of the Japanese attack on Pearl Harbor that led to U.S. involvement in World War II.


Always a roaring loud and fun time, Slinger Super Speedway features a variety of races with plenty of action. The surrounding terrain is nice, too.slingerspeed2_500


A old postcard showing Slinger, where Highway 144 ends. Or starts. Depends.
Today’s downtown Slinger is marked by the intersection of Highway 175 and Highway 144’s terminus, which connects to I-41. A lot of fantastic stone construction is evident in the surrounding buildings. Check it out!
St. Lawrence Church, built in the early 1880s.


After Slinger comes the little crossroads of St. Lawrence, which features a historic and charming chalet-looking fine dining restaurant called the Little Red Inn (4900 Hwy 175, 262-644-8181), a bar called the St. Lawrence C-Way (clever, no?), and the gracious St. Lawrence Church (1880-82), featuring loud chiming bells that echo through the burg.

The Little Red Inn hugs the corner of Highway 175 and County K as St. Lawrence’s other landmark.

Just north of tiny St. Lawrence, 175 intersects with the former north terminus of Highway 83, which blends right into the roadway if you’re going northbound. The former Highway 83 doubles back to Hartford where it starts up again and heads all the way back down to Illinois. But we’re forging northward on the “old 41” Highway 175 route, so onward!

The view from northbound Highway 175 between St. Lawrence and Addison looks across a valley holding the North Branch of the Rock River and the Theresa State Wildlife Area toward hills in Kettle Moraine’s Northern Forest Unit. Fertile farmland abounds in this area.
Farms abound too, and many are tucked into small valleys that line Highway 175. Watch for slow-moving farm vehicles at times, which must have caused massive backups way back when this was U.S. 41, the main road from Milwaukee to Appleton and Green Bay.


After skidding west of Addison in a new alignment past Highway 33, you enter the village of Theresa (pop. 1,252), pronounced “ther-ay-sa”. Theresa holds the distinction of being named after the mother of Solomon Juneau, who’d founded this other place called Milwaukee years earlier, moved out, established Theresa, and therefore was the first European settler to begin urban sprawl in Wisconsin.

The downtown area features a variety of “old-school” buildings, including a series of signs that have been up since this was U.S. 41.

widmers_800Cheese store alert.

A longtime State Trunk Tour favorite, Widmer’s Cheese Cellars has been producing a variety of cheeses in Theresa since 1922. Specializing in Wisconsin native cheeses brick and colby, Widmer’s 12,000 square foot facility uses the same open vats and well-worn bricks that press the whey used since Widmer’s opening. The facility includes a small store area with a full view of the cheesemaking area. A quick left on Henni Street right past Solomon Juneau’s cabin will bring you there. Stop in, take in the scent of cheese being made (not for everybody) and load up on fresh curds – that’s what the State Trunk Tour does. They offer tours but times can vary, so check here for details.

Solomon Juneau first founded in Milwaukee, then fled in later years to establish Theresa, named after his mother. His final homestead, built in 1848, is along Highway 67 in town, where it also meets with Highway 175.
The section of Highway 67 combined with Highway 175 is part of the historic Yellowstone Trail, a trailblazing path through the early days of American driving.


Not as early as the Yellowstone Trail but still becoming a slice of old Americana are the old logos on signs, such as the one for 7Up on this store in Theresa.

In Theresa, Highways 67 and 28 join 175 just past the Rock River crossing. All three highways head north for a few miles before Highway 28 breaks east toward Kewaskum; Highway 67 stays until Lomira, when it heads east toward Plymouth.

A then vs. now shot of today’s Highway 175 approaching the Highway 28/67 turnoff in Theresa, Wisconsin. In the older photo, this was still the original U.S. 41 route, which means it was prior to 1954. Then, as now, it’s also the route of the historic Yellowstone Trail.


Lomira (pop. 2,233) is one example of a town that was once focused on this road when it was U.S. 41, but now most of the activity and development lies further east along the busy freeway that is today’s I-41. But where the freeway view of Lomira reveals gas stations and fast food restaurants, Highway 175 offers a slower, easier ride, smaller, quaint structures, a variety of homes and the attractive St. Mary’s Catholic Church. A lot of nice old churches adorn this road.

State Trunk Tour Tidbit:
The massive Quad Graphics plant in Lomira is the largest single printing facility in the Western Hemisphere.

The stretch from Lomira to Fond du Lac is straight as an arrow, paralleling I-41, which lies about a quarter mile to the east. You pass the Quad/Graphics plant near Highway 49, and a sign of the future around Byron: giant turbines providing wind-generated electricity.

Anderson Garage along Highway 175, the old US 41 south of Fond du Lac
Anderson Garage, which indeed has been operating as a car repair shop since 1918, when some people were still using the term “horseless carriages.” You’ll find it just north of County B in Fond du Lac County.

Highway 175 also negotiates a ridge on its path; the view to the west stretches for miles and miles, as does the massive wind farm. Over 80 wind turbines churn in this territory – a since they all have those red aircraft warnings lights on top, it’s quite sight a night. During the daylight, just past the intersection with County B in Byron, you can look north and see parts of Fond du Lac and Lake Winnebago, ten miles away.

Highway 175 view towards Fond du Lac
Lake Winnebago and parts of Fond du Lac are visible from Bryon along Highway 175, almost ten miles away.
North end of Highway 175, approaching U.S. 151
Highway 175 ran through Fond du Lac and all the way to a junction with U.S. 45 just south of Oshkosh until 2007, when it was scaled back to the new U.S. 151 bypass around the south end of Fond du Lac. For the purposes of this tour, we’ll head into Fond du Lac until we reach Lake Winnebago.

Past today’s end of Highway 175 at the U.S. 151 bypass of Fond du Lac, you leapfrog over I-41/U.S. 41. Just past there is the Kristmas Kringle Shoppe, where it’s always Christmas and people stop in from all over the country. You want Christmas in July? It’s here.

Fond du Lac

That’s your gateway to Fond du Lac (pop. 42,203), entering a city whose name literally means – in French – “bottom of the lake.” The lake – of course – is Winnebago, one of the largesst inland lakes in the United States. Fond du Lac is the home to Mercury Marine, Marian University, the “living museum” of the Galloway House and Village, and a downtown that’s rather vibrant for a city this size. The former Highway 175 (and U.S. 41, remember) is Main Street in Fond du Lac, running right up through downtown. You can choose one-way alternate routes around the downtown strip, where U.S. Highway 45 joins, or run straight up Main Street to get the full flavor of shops, restaurants, and some good old architecture, much of which dates back to the late 19th century.



Straight up Main Street, downtown Fond du Lac offers up a long line of great old buildings with 19th century architecture. Storefronts are full and it’s a great place to park and walk around. By the way, if you buy lottery tickets, do it in Fond du Lac. Since the 1990s, a number of winning Powerball jackpot tickets have been sold along Main Street, prompting many to dub it the “Miracle Mile.”

State Trunk Tour Tidbit:
Fond du Lac is in the Guinness Book of World Records for having created the world’s largest working fondue pot (8 feet in diameter, can hold 2,500 pounds of melted cheese) during their Fondue Festival in 2007.

Between downtown and Lakeside Park, you cross Highway 23, a major east-west state road, and the cool collage painting on the south side of Mike’s Music & Sound.

Can you identify ’em all? The collage along Mike’s Music & Sound on Main Street in Fond du Lac.

The old Highway 175 turns left onto Scott Street, at the entrance to Lakeside Park. A good diversion is to head straight into the park and enjoy the southern shore of Lake Winnebago. Being the “bottom of the lake” city, Fond du Lac sits on the southern end of this largest inland lake in the state, and one of the larger lakes in the nation; the north shore, near Appleton, is 30 miles away.

  1. Hi Glenn! I’m actually working on adding the U.S./Interstate Highways to this, and including their historic routes. They’re not posted yet.

    I can tell you that the original Hwy 41 route through Appleton came in from Neenah and Menasha on Tayco and 3rd Streets, then up DePere Street and Appleton Road on what is today Hwy 47. Hwy 41 entered downtown Appleton via a crossing on today’s Memorial Drive, then turned east on Wisconsin Avenue, today’s Hwy 96. It followed today’s Hwy 96 to where Riverbend/Edgewood have a junction with today’s I-41. The original road followed roughly today’s highway path into De Pere. From De Pere it headed north on 8th and then today’s Ashland Avenue (today’s Hwy 32) into downtown Green Bay. From GB, it hooked up with Mather and Velp and followed today’s U.S. 141. It continued on today’s Velp (County HS) through Howard and Suamico and on north via today’s County S and today’s “Business 41” routes through Oconto and Peshtigo into Marinette. Another note: before U.S. 41 was designated in 1926, that road was the original Wisconsin Highway 15.

    Does this help? Any other info I can provide? I appreciate your checking out StateTrunkTour.com – it’s still being built!

  2. I came across this looking for the original Hwy 41 route from Appleton thru Green Bay. Does this site have any such thing??
