Photograph of concrete viaduct over a street, showing automobiles below the viaduct, [s.d.]. In the foreground at center, a wide street can be seen extending from left to right. On the opposite side of the road at center, a large utility pole stretches past the top of the image. To the left, a large concrete viaduct can be seen over the road extending into the background at right. Small lampposts line the edge of the viaduct. Concrete, arched columns support the viaduct from the road. Below the viaduct, at least four automobiles can be seen near some of the columns. In the extreme background at right, the viaduct can be seen leading to a large tunnel in the side of a mountain.
