A look back to happier times in the San Gabriel Mountains. Taken on August 22, 2009, just a few days before the Station Fire started. Over the past few days, this section of the mountains has burned in the Bobcat Fire, which is ongoing.
In 1958, when the East Los Angeles Interchange started to be built, the routes that were planned to go through it were a little different that what is there today. I-10 was originally to be State 26 and I-5 was a part of US 99. US 101 remained the same. State 60 was to be State 26. The routing of the interstates through cities wasn’t quite settled yet and many of the roads were planned to be State or US routes.
After the signs were installed, some of them were temporarily overlaid until the Pomona Freeway connections were completed. A portion of the original route planned for that freeway, State 26, was visible. While some have speculated it was actually US 60 underneath there, reverting to State 60 after the 1964 route renumbering, these plans show otherwise. How far east the State Route 26 signage would have gone does remain unknown. It is likely it would have gone at least as far as the 57, if not all the way to the 71, as US 60 was effectively terminated at the present junction of I-10 and State 71 about 1960.

Looking toward South Mount Hawkins in the West Fork San Gabriel Canyon from State 39. This road was planned to be improved but landslides prevented this work from being completed. In the case of this area, almost all of the low lying areas not covered in snow are landslides in one form or another. Even Crystal Lake, where this roadway is headed, exists because of landslides.
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.
I-5 between Santa Clarita and the San Joaquin Valley is commonly referred to as “The Grapevine” by locals and traffic reporters. Most assume the name derives from the twisty nature of the original roadway – the Ridge Route. That road was indeed very twisty, much like a grapevine. However, that is still not the reason. The name Grapevine actually comes from Grapevine Canyon, where old US 99 and I-5 come down from the mountains and into the San Joaquin Valley. The canyon is called such as wild grapes grow along the canyon walls. It was formerly known as Canada De Las Uvas which is Spanish for Canyon of the Grapes. The name Tejon Pass is also a “new” addition to the area. The current Tejon Pass was known as Grapevine Pass or Badger Pass until the 1850’s. Old Tejon Pass, much farther to the east, was a very treacherous route. That pass was eventually abandoned in favor of the current Tejon Pass. The name was just shifted to the new route.
After the 1933 bypass of the original road to as late as the 1970’s, the roadway over the mountains was still referred to as “The Ridge Route”. It wasn’t until the 1980’s that the name “The Grapevine” was extended to the entire roadway. Why this was done is still unclear. Even Caltrans called it the “Ridge Route” when I-5 was completed. So, if you want to call it proper – call it Tejon Pass, when being specific to the actual pass, and the Ridge Route when referring to I-5 from Castaic to Grapevine. While you’re passing through Grapevine Canyon, be sure to spot the wild grapevines that still grow in the canyon. Names may change, but the name Ridge Route should live on. It applies to I-5 better than “The Grapevine” ever will.
