Bridge Inventory Inspection Records
Arrangement: numerically by bridge number
Series documents inspections conducted by the Highway Department of bridges in most Oregon counties from ca. 1941 through 1945. Records include one inventory sheet for each bridge with one to three attached photographs. Information on the inventory sheet includes name of waterway over which bridge crosses; road and mile number; county; inspector's name; date; and bridge number. Bridges of all sizes and designs (log, covered, etc.) are included in the inventory. The records are arranged numerically by bridge number. This also corresponds largely with arrangement by county.
5 boxes of processed photographs (#12,000-#13,749) are also available.
NOTE: A searchable database of these photos is available. Please contact us for details.
