As a way to keep track of the immense amount of data regarding old highways, I created highway logs to store the data. They were originally designed after 1940’s state highway logs from the Division of Highways. I have made them available on this website on my Site Documents page. The logs for US 6 and US 99 have recently been updated and have been uploaded.
- US 6 Route Log – Newhall Pass to the Nevada State Line near Benton, CA
- US 99 Route Log – Mexican Border at Calexico, CA to Delano, CA
