PTH 68 first appeared on the 1952 Manitoba Highway Map. Originally, the highway served as an east-west connector route within the
Interlake region between PTH 8 and PTH 6 at Eriksdale. In 1987, the highway was extended to its current westbound terminus, replacing
PR 235 between
Ste. Rose Du Lac and PTH 6.{{cite web ==Major intersections==
