The history of the A 4 dates back to the 1920s. Initial plans envisioned connections between Aachen and Cologne. Construction began in the 1930s. This early vision laid the foundation for the modern Autobahn system. In 2014, a section of the A 4 between Cologne and Aachen was rerouted. This change was due to the expansion of coal mining.
