Beginning with the first industries developed in the 1830s, which were mainly for processing materials grown in

In Wisconsin , county highways are marked with letters—with one- to three-letter combinations (i.e.: C, CC, or CCC).

Previously, the roads simply had road names, such as "Essex Road 42" or "Kent County Road 14", and so on, but had no markers to designate them. Many Ontario county roads are built to provincial highway standards, as thousands of kilometres of highways were downloaded from
