Pre-1945 state roads 64-100

One useful source is a 1939 list published by the SRD. I had previously taken notes on all the laws, but this combines them in one handy booklet.

Note that many of the legislatively-defined routes were never built or never acquired by the state. This is especially true of higher numbers.
