Records (1935-1991) of the Montana Department of Highways, Great Falls District Office, consist of the correspondence, meeting minutes and subject files of the Great Falls District and area offices, including the Havre Area Office. The records include correspondence files (1935-1993), subject files (1941-1997) and meeting minutes (1997-1998). Subject files are primarily correspondence which relate to specific subjects.

Both correspondence and subject files document: general and special maintenance projects of highways, bridges, and signs; public concerns; municipal concerns and projects; Federal and State grants and funding, including Works Project Administration era projects; civil defense and transportation concerns; accident and safety monitoring; as well as district budget and project planning. A large portion of the files document flood damage, flood control, and repair projects.
