This photo shows Highway 40 at the intersection with Elm Street in Auburn, California. It looks like the car at left is merging onto the freeway, while the truck with trailer heads on down the road.
Today Elm Street crosses over Interstate 80 via a bridge.
The above photo is a close up of the truck with a trailer. The brand “Betsy Ross” is emblazoned on the truck and trailer. Yes, those are pedestrian crosswalks in the close up below.
