I can assure you, this is not the Pasadena Freeway. Way too many lanes... This is a photo of the Pasadena Freeway. Actually, it is not and never has been a Freeway. It's real name is the Arroyo Seco Parkway (California State Route 110).
The photo I posted is part of the Arroyo Seco Parkway aka Pasadena Freeway or as it was once numbered SR11. This location is just before the four level interchange heading into downtown. I have driven that section countless times when I lived in So Cal.
Thanks for your answer with the pictures. I thought they were Impala's. Nomads will always be 55,6,7 Chevys
Well, I have lived in SoCal for 83 years, and drive the SR-110 two to three times a week from Pasadena to downtown L.A. The Arroyo Seco Parkway is 3 lanes in each direction. The other photo is the six lane part of the interchange, which eventually merges into the SR-110, which continues through downtown L.A for 33 miles, terminating in San Pedro at the harbor.... Three lanes in each direction. It was three lanes in 1940 and it's still three lanes.
