As a child, road maps drew me in. The lines on the map fascinated me, linking places I had never been to or heard of together. Numbers linked with the lines created journeys for discovery. In 1926, the federal government came up with a plan to number highways to replace names – in this case, the Pacific Highway – in order to establish an integrated system of roads throughout the country. The so-called “Federal system” did not mean the federal government built or maintained the roads. That process remained the responsibility of local and state governments. Highways simply gained numbers and signs so auto drivers could determine their location.
