Crossing into Los Angeles County

Northbound left exit for Firestone Blvd, former SR-42. This was near where I-105 was planned to end. Firestone Blvd also carried US 101 Bypass, until the construction of the Santa Ana Freeway through here in 1953.

At Norwalk Blvd, the greenout covers a SR-35 shield. State Hwy 35 used to be a Los Angeles area roadway until 1964, having been functionally replaced by I-605, it was moved to the San Francisco Bay area, there replacing SR-5 (Skyline Blvd).

Approaching I-605 NB

Going northbound through the "Mixmaster" Interchange. Atlantic Blvd was formerly the route of SR-15, which the Long Beach Freeway replaced. There is no direct connection to I-710 SB, only NB.

Santa Ana Freeway near Indiana Street in 1948.

Large parts of this freeway were built in the 1950's and early 1960's. Some of the bridges crossing it are even older :

Hyperion Viaduct in Glendale. Built 1928.

Older railing left in the median of the freeway near Alameda Avenue.

Sometimes the greenout will fall off, revealing older routings of highway numbers. Route 134 now runs along a portion of the Ventura Freeway. This sign has since been repaired.

Freeway southbound near Sheldon Street in the San Fernando Valley. This section was completed in 1963.

Northbound at the Antelope Valley Freeway (SR-14) interchange.

View of the 5/14 interchange from the Weldon Canyon OC. This half of the bridge has been unused since around 1972. View is looking southward. Closest flyover ramp connects SB I-5 to NB SR-14. A span of the old (1975) 5s-14n connector did collapse in the 1994 Reseda/Northridge earthquake.

I-5 northbound just south of Magic Mountain in Santa Clarita.

Route 5 in Orange County
