Former US Route 99 north from Hornbrook to the Oregon State Line

[Max Rockatansky]

I stumbled on some CHPWs that I needed to finish documenting the former corridor of US Route 99/Legislative Route Number 3 from Hornbrook north to the Oregon State Line.  Rather than starting a new blog I just included the new materials into the existing post regarding OR 273 over Siskiyou Pass.  Notably US 99/LRN 3 was moved off Hornbrook Highway during 1949.  There is some further details about when US 99 moved off Jefferson Road and when I-5 was finished on the California side:
