Starting at US 151/CTH-J in Valders, WIS 148 began to travel northward.

At this point, WIS 148 ended there, and the roadway continued as CTH-J.

[5][6] 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 (replaced by CTH-J).

The entire highway was in Manitowoc County.
