Here, the old Ridge Route and US 99 separated. The Ridge Route was completed in late November 1915 and US 99 was completed in 1933. One can see here the 3-lane “suicide” lane highway that parts of old 99 once were. This town was founded in 1915 as a rest stop along the Ridge Route. Now its a major truck stop along I-5. The next major stop is in Gorman.
