The organized system of Wisconsin State Trunk Highways (typically abbreviated as STH or WIS), the state highway system for the U.S. state of Wisconsin, was created in 1917 with the original numbers starting at 11 and up to 199. These routes were altered significantly in 1923 when United States Numbered Highways were commissioned. Further alteration occurred when the Interstate Highway System was commissioned in the state.
Wisconsin highway markers use the FHWA Highway Gothic font in Series D for all one- and two-digit numbers and Series C for three-digit markers. All highways except Interstates use 24-by-24-inch (610 mm × 610 mm) or 36-by-36-inch (910 mm × 910 mm) markers; Interstate markers for three-digit highways are wider shields.
