The Specific Information Sign Program was started as a result of the 1965 National Highway Beautification Act . To date 47 states have active programs with 25 states contracted by private enterprises.
In 1986, Wisconsin was the second state that elected to use the Specific Information Sign (SIS) Program established by the Federal Highway Administration. This program was designed to replace generic blue and white signs directing travelers to "Gas”, "Food”, "Lodging ”, "Camping” and "Attractions” services. The SIS Program provides more information to the traveler by providing signs with logo panels of specific businesses found at a given exit. The SIS structures carry up to six business panels per service category. These signs are located on approximately 3,000 miles of State trunk system and vary according to road size. Milwaukee County is excluded from this program. The type of road determines the physical size of a sign structure and business panel. Interstate signs are larger than conventional highway and exit ramp signs. Click here for some interesting Wisconsin highway facts.
The program is regulated by the Wisconsin "Highway & Transportation Laws & Rules” Manual, section 86.195 and Trans-200.06 also on the national level by the " Manual on Uniform Traffic Control Devices ”.
