Scope :
These files constitute a record of highway bridges built by, transferred to, or eliminated by King County between 1901 and 1994. During this period, bridge engineering was undertaken by the County Surveyor (1901-1907), County Engineer (1907-1937, 1949-1969), Road Engineer (1937-1938), and the Department of Public Works (1938-1948, 1969-1994). The files document these agencies' construction, inspection, maintenance, repair and replacement of bridges and of railroad and highway overcrossings and undercrossings. Record types include construction documents (e.g., cost estimates, contractor estimates, engineering notes and calculations, contract documents); inspection reports; correspondence; structure plans, site maps, and shop drawings; newspaper and journal articles; and photographs. Photographs and negatives have been removed (see Series 103-474, Road Engineer bridge files: photographs, 1904-1988). Many maps, plans and drawings also have been removed, although some remain in the text files. These files originally comprised three subseries: (1) bridge files maintained by the Road Engineer; (2) bridge files maintained by the County Engineer and the Department of Public Works; and (3) files for bridges eliminated by the county through demolition, replacement, or transfer to another jurisdiction. These subseries have been partially interfiled. One subseries of road engineer job record cards and cost estimates for eliminated bridges remains at Box 32. Files in boxes 1-17 and boxes 32-39 are arranged in ascending numerical order by the county's bridge identification number. Boxes 17-31 suggest a chronological order. Files in box 32 are arranged by a separate three-digit bridge inventory (B.I.) number; cross-reference is made to each bridge's original identification number.
