The route headed northwest for about one mile (1.6 km) until curving to the north, crossing over Wolf Creek, and ending at SR 2 which was also known as Toledo–Wauseon Road.

[1][2] The entire route was in Springfield Township, though the northern terminus was located just outside the village limits of Holland.

[citation needed] The short stretch of road had been a part of the state highway system since at least 1912.

[5][6] In 1927, the mile-long roadway became the entirety of State Route 223 as the roads north and southeast of the southern terminus became a part of US 20.

[10] SR 326 would only be signed for about two years because in 1934, the route was removed from the state highway system altogether.
