City of San Diego – 1970

The City of San Diego Clerk has been placing a large number of videos on YouTube over the past few months which are quite unique and eye-opening. In 1970, the City created videos of many of the roadways in San Diego. These are done in the same manner as Caltrans Photologs, which essentially takes a photo of the road every few feet or so, creating a fast motion video of the road. Roads such as Murphy Canyon Road and Kearny Villa Road no longer exist in the same manner as they did back then. Both have been greatly modified by I-15 and State 163. Some of the street names don’t match current names, however. Black Mountain Road, as shown in the video, is basically Del Mar Heights Road and Landsdale Dr, among others. Miramar Rd, in the video, covers current Eastgate Mall as well, as it was the old alignment of Miramar Rd through to UCSD.

These videos show this and more. Why not see it for yourself and be amazed! Try and count the number of spinning gas station signs too.

1932/34 concrete at the divergence of the lanes at Grapevine.

Here at Grapevine, a small section of concrete is visible adjacent to the southbound lanes of I-5. This is a section of former US 99. A small color difference can be noticed between the two lanes that are visible. This difference is due to age. The lanes to the left were constructed in 1932 when Grapevine Grade was realigned, bypassing the original 1914 Ridge Route grade. This was built as two lanes as a temporary measure to expedite the opening of the new route. Right after it was opened, a third lane was added, the lane on the right, creating a three-lane roadway with a common passing lane in the center, or “suicide lane”. This condition persisted until 1943 when the road was widened yet again to four lanes. In 1959 – 1960, these lanes were bypassed by the current southbound lanes of I-5. Today, they remain as one of the last remnants of the 1932-1959 version of Grapevine Grade.

Caltrans Sign Change

In June 2019, I sent a message to Caltrans requesting a change in the signage on I-805 northbound at El Cajon Blvd. The sign didn’t reflect the lane assignments and can be confusing to motorists not familiar with the interchange. In November, I got a response and they will not only change the sign but …
