From the Archives – 1956

The first section of the San Diego Freeway in San Diego (US 101 at the time) to be constructed was the Mission Bay Bypass in 1954. Elements of this construction can still be seen today, such as some older curbing at the intersection of Damon Ave and Santa Fe St. North and south of this small section of freeway, it was still a narrower four-lane roadway with some expressway sections. Between 1966 (north) and 1969 (south), the adjacent sections were constructed, completing I-5 in the City of San Diego.

Website Updates

Over the past week or so, I’ve been working to add more content to the site. Not to avoid completing the existing pages either, just to fill in some gaps. Here are some of the updates:

  • New Website Feature – a new Discussion Forums feature has been added. It is an experiment, so we’ll see where it goes.
  • New SectionCivic Information – These pages give links to every incorporated city in Southern California and give a bit of information about each county as well. The links are finished, but the format is still being worked on.
  • New PageSeeking Old Highways – A while back I was working on putting up a guide to looking for old roads, bridges, and signs. It is still a work-in-progress, but has now been more given its own page in the Highways section.
  • Additional Historic Photos – Old photos of US 101 in the Los Angeles area have been added to the US 101 page.
