Salt Lake Division Bridge Inspection Books

From: "Michael Polk",

I am an archaeologist who has been doing archaeology and historical research on the Promontory Branch of the Central Pacific for 30 years. The bridge inspection books for the Salt Lake Division are one source that is exceedingly useful, but my search for them has been limited. I found one 1920 book at a warehouse of the UP in Omaha in 1998 and was told that the remainder resided at two small warehouses, one in Mountain View, California, known as “File Safe” and another in San Francisco. This was during the time that UP was consolidating SP into their system, so I have no idea if they are still there or moved to Omaha or elsewhere and how I might access them.

Does anyone here know where the bulk of the Salt Lake Division Bridge Inspection Books may reside now? I would really appreciate any suggestions. ...
