Interstates Turn 50: Additional Historic Photos


WarningNote: The “Interstates Turn 50” series of pages were originally published on the Caltrans website in 2006. They disappeared from the site in June 2019. Knowing that of the goals of this site is to preserve information about the state highway system, and that includes information that was once on the Caltrans website but later disappeared, a friend from Caltrans requested that I explore saving these pages. Luckily, the pages in this series were preserved in the Internet Wayback Machine, and Caltrans has not asked the Internet Archive to take them down. This is because Caltrans is good about giving permission to use photos for nonprofit use. The images here used to be right there on Caltrans' publicly accessible site, and are posted elsewhere around on hobbyist sites. Still, if you wish to use an image, please formally request the image from Caltrans, and indicate you saw it…on the Internet Wayback Machine
