The first plans for the Cologne-Düsseldorf route go back to 1925. In 1929 the Provincial Association of the Prussian Rhine Province legally established the route between Cologne-Düsseldorf and in 1931 the construction started of a 2.5-kilometer section at Opladen. I was opened on 27 September 1933 and shortened the section of trunk road 8 between the two cities. The southern part of this route was not further upgraded and included in a simple bypass, now part of the B 8 / L 288 (Bonner road).
