History
The alignment of Route 478 began in the 1928 numbering of state highways as an unnumbered state highway. However, the next year, the alignment was designated as part of Pennsylvania Route 238, which ran from Saint Petersburg to Shippensville. This lasted only seven years, when Route 238 was realigned to terminate in Mariasville. In 1936, the alignment was replaced with Route 378, which remained intact as its alignment designation until 1961, when Interstate 378 was designated for a freeway in Bethlehem. To avoid duplication, Route 378 was replaced with Route 478, a designation that had been unused until that point. The alignment has remained intact since.
