Sepulveda Blvd. Junction (State 7)
Sepulveda Junction. I-5 / I-210 interchange is in the background.
At Sepulveda Junction, SR-7 branches 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.

Sepulveda Junction and the I-5 / I-210 Interchange in 1999. I-5 is the through freeway.
San Fernando Road follows the railroad tracks, Sepulveda Blvd follows the Golden State Freeway from I-210 south. I-210 is the freeway heading northeast.
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.
