Malheur County Records Inventory

Road and Bridge Records

1887-[ongoing]

Series documents the development, construction, maintenance, and improvement of county roads and bridges. Records include bonds, general road and highway maps, petitions to have roads constructed or altered, notices, complaints, vacation records, and correspondence. Information includes road numbers and names and descriptions of the activity occurring on the road. Information concerning county roads may be available on the Integrated Road Information System (IRIS) at the county road office. Technical road survey maps may be found in the series titled Road Maps and Survey Notes.

The Malheur County Road Department Building burned in 1949 leaving few records about county roads and bridges. In 1978, the county conducted a project to gather information such as petitions and vacations about county "dedicated" roads from the County Court Journal-Commissioner's Proceedings (Commissioners Administrative Journals). Information about "non-dedicated" roads (roads obtained through deeds, etc.) has been compiled also.
