Glacial Lakes State Park is located on Highway 29 in Pope County.

[7][8] South of Alexandria, it was paved to the county line in 1931,[9] and to a Northern Pacific railway crossing at Glenwood in 1933.

[10] Also in 1933, the highway was realigned between Deer Creek and Wadena, providing a shorter, more direct route.

[1] It was paved with concrete through Benson and several miles north and south of that town at the time it was marked.

[21] When Interstate 94 was built through Douglas County in 1967, Highway 29 was upgraded to four lanes from the freeway north into Alexandria.
