This image shows the typical shelters and parking area common to rest stops along the Interstate Highway system. These are in fact custom, and not nationally standard, as each state has its own contracts to build the rest areas.
The description states:
Interstate 80 in Nebraska has many beautiful rest areas for the comfort and convenience of travelers.
–The shelter in the foreground has a bench were travelers have apparently deposited some of their belongings, and there is a fire pit on a stand just to the left of the brick wall. The cars in the image indicate this card is from the 1960s.
