The further expansion up to the cross Leverkusen is in the federal traffic route plan (BVWP) with the status urgent need. From the investment framework plan for the years 2011 to 2015 of the Federal Ministry of Transport, Building and Urban Development, the view was expressed that for the reconstruction of the AK Leverkusen and the expansion between the interchanges Leverkusen Center and Cologne-Mülheim, the planning should be promoted priority to start construction by 2015. The planning approval decision for the eight-lane expansion in the section from Cologne-Mülheim to AS Leverkusen-Zentrum was available at the end of January 2012. The eight-lane expansion between AS Köln-Mülheim and AS Leverkusen has been open to traffic since June 2, 2017. The expansion between AK Leverkusen and AS Leverkusen-Zentrum is considered to be another important project with a realization after 2015. This further expansion of the A3 is also in direct functional connection with the expansion / conversion of the A1 between the Rhine bridge Leverkusen and the interchange Leverkusen and should therefore probably be realized together.
