This picture features a common subject of the west in the early post World War 2 period: pictures of highway construction. Among the favorites were pictures like this, of winding roads that climbed and descended complex mountain and valley routes.
This picture appears to have been taken near the side road that led to the Gold Road mine. The color in the upper center is a printing error for this image.
There is no description on the back of this card, but the image dates from the 1940s.
