History
In 1924, WIS 148 was established along present-day CTH-J from WIS 31 in Valders to WIS 18 in Cato. During its existence, nothing significant has happened to the routing. Around 1985, WIS 148 was removed in favor of transferring this route to local control. There have been no WIS 148 designations ever since.
