For Star Route contractors, the "best" technology was the one that fit the route. Over the years, Star Route mail carriers have discovered many diverse and effective methods of moving the mail. In 1948, the Post Office Department began experimenting with long-haul trucking for Star Routes. Today, these routes cover more mileage than any other category of mail transportation and move 90 percent of the U.S. mail.
These postage stamps are examples of many issued by the Postal Service to commemorate methods of transportation used to move the mail.
