Tips on Entering Highways

When the roadway has two or more highway designations, choose the highway with the highest classification.  Order of hierarchy:           

• Interstate highway

• U.S. highway

• State trunk highway

• U.S. business route

• State trunk business route

• County trunk highway

• Local streets or roads

For example, USH 41 and IH 94 run concurrently in Kenosha County.  In this case, 94 should be chosen as the On Hwy # because an interstate highway is higher in the order of hierarchy than a US highway.

When the roadway has two or more designations of the same classification, choose the lowest numbered highway.  For example, interstate highways 39, 90 and 94 runs concurrently for a while in Dane County.  In this case, 39 should be chosen as the On Hwy # since they are all highways with the same classification and 39 is the lowest-numbered one.

If the highway you're looking for isn't on the list, check that you have the correct county and municipality selected in fields 2 and 3.  In many counties, there is a township and city or village with the same name.  If you have double-checked the county and municipality and have followed the rules above for selecting highways with more than one designation, and it’s not a county highway within a city or village (in which case it should be entered in the On Street Name field), enter it in the On Street Name field by keying Alt + O or selecting the "Other" button on the tool bar and then keying STH, IH, USH, or CTH plus the number or letter.  You will get a warning about this, but you can still validate the form.

Please make every effort to select the highway from the list rather than keying it in the On Street Name field.  Other data fields such as highway class are added to the data behind the scenes based on the value in this field.
