[1] The highway is a gravel road except for small paved sections near the eastern and western terminuses.
Highway 25 is part of the original Provincial Highway 3, which from Melfort travelled west to St. Louis, crossed the South Saskatchewan River via the St. Louis Bridge, and travelled concurrent with Highway 2 to Prince Albert.
[2] In 1970, Highway 3 was realigned to the newly constructed Muskoday Bridge and the bypassed segment between Birch Hills and St. Louis was renumbered to Highway 25.
North on Highway 2 is the city of Prince Albert while south is Wakaw.
From Hagen, it takes a north-easterly route to Birch Hills and its eastern terminus at Highway 3.
