At Sepulveda Junction, SR-7 branched off to head toward the central San Fernando Valley. US 6 / US 99 heads southeast here toward Sylmar and San Fernando. This was the equivalent to the I-5 / I-405 freeway interchange of today just south of here. Today, I-5 and I-210 meet here.

The structure subsequently partially collapsed in the 1971 Sylmar earthquake. This location would now be at the I-5 / I-210 interchange. Courtesy – Caltrans

Before 1937, US 6 stopped in Denver, Colorado. What is now SR-14 was SR-7. It ran along the alignment of US 6. In the same year, SR-7 was realigned when Sepulveda Blvd. was extended from Brand Blvd. to San Fernando Road at the point shown in the photo. Most of that extension is buried underneath I-5 from I-405 to here. The modern interchange collapsed in the 1971 Sylmar Quake.
