About the Wisconsin Trunk Highway System
Wisconsin was the first place in the world to number its highways. The numbered system was enacted in 1917 to replace the unofficial auto trails that were cluttered and confusing for motorists. The numbered system made it easier for motorists to travel, and was soon adopted by the rest of the nation and the world.
Wisconsin also has a unique lettered county road system. Started in the 1920s, counties laid out a lettering system for their maintained roads. Eventually adopted by the state, the letter designations can be 1,2, or 3 characters long. Lettered routes can be used multiple times throughout the state.
County trunk highways can be lettered just to give a road a designation, or they can can have meaning. For example, County HS in Brown County was named because it passes through Howard and Suamico.
During the late 1980s, Wisconsin adopted a 2020 Highway Plan. This laid the groundwork for Wisconsin’s present transportation system with a goal of improving routes within the plan by 2020. Consisting of a 1550 mile system of freeways and expressways, the plan outlined linking major population and economic centers. A 2100 mile subsystem of high quality two lane and four lane roadways that connect key communities throughout the state compliment the backbone system. The final backbone route upgraded within the plan was U.S. 41 between Oconto and Marinette in 2009.
The Connections 2030 plan is a revised version of the original 2020 plan. It was enacted in 2009 to provide updates and revisions based upon Wisconsin’s Transportation needs.

- Geography and climate: Various glaciations over time was the primary cause of the rolling topography that makes up Wisconsin today. The northern part of the state sees higher elevations (varying from 1,000 feet to 1,900 feet). The majority of streams and rivers in Wisconsin originate in these higher elevations. A good portion of Wisconsin typically has warm summers and more often freezing winters. The northern reaches of the state often remain within freezing temperatures for the majority of the year, with perhaps only a month or two without any freezes. The southern half reaches a more temperate climate with an average of 180 days of non-freezing conditions. Lake effect snowfall accumulation can peak around 100 inches in areas such as Ironwood along the Wisconsin/Michigan border
- Usual claim to fame: Lambeau Field is often referred to as “The Frozen Tundra”, originating from a 1967 NFL Championship game between the Green Bay Packers and the Dallas Cowboys.
- Other interesting tidbits: Old Milwaukee, Old Milwaukee Light and Pabst Blue Ribbon beer were all established in Milwaukee in the 1800s; famous actor and narrator, Orson Welles, hailed from Kenosha while famed architect Frank Lloyd Wright was born in Richland Center (Richland County); Wisconsin is also home to over 20,000 miles of snowmobile trails and to the largest cross-country ski race held in the United States.
