After Napoleonic Wars and the Empire's dissolution in 1806, the Prussian monarchs systematically expanded the road network, completing the chaussee between Berlin and Magdeburg in 1824, and between Berlin and Königsberg in 1828, reaching the East Prussian terminus at Gumbinnen (present-day Gusev, Russia) in 1835. In 1932 the major highways of the German Reich were numbered and two years later the "Fernverkehrsstraße 1" was incorporated into the "Reichsstraßen" system. After 1945 the former "Reichstraße 1" was split into "Bundesstraße 1" in West Germany and "Fernverkehrsstraße 1" in East Germany until 1990. The part east of the Oder became part of different polish "Droga krajowa".
