3. A2 between the Bottrop interchange and the Oberhausen interchange
In this section, the entire roadway will also be renovated beyond 2023. With the very high traffic volume there of around 120,000 vehicles per day, traffic jams – caused by the lanes being narrowed in the construction area – are difficult to avoid, says Autobahn GmbH. “The traffic jam sometimes extends back to the A31.”
4. A3 motorway junction Cologne-Heumar
All bridge structures here will have to be replaced by 2029. Work on replacing the existing KVB bridge has already begun. Since mid-October 2021, there have been two narrowed lanes in each direction at the level of the A3/A4 ramp. All four lanes were transferred to the lane in the direction of Frankfurt. This traffic routing is expected to remain in place until the end of 2023.
5. A3 between the Breitscheid and Oberhausen motorway junctions
In this section of the A3, the Kaiserberg motorway junction will be expanded from the beginning of 2023. In order to make the highly frequented junction fit for the future, Autobahn GmbH Rheinland is renovating all routes, bridges and ramps here. In addition, both motorways will have an additional lane in each direction at the intersection. “This is intended to improve the traffic situation in the junction, which is already heavily used and prone to traffic jams and which will be even more frequented in a few years’ time.”explains the GmbH – according to its own statements, Europe’s largest motorway operator. “The extensive work requires several traffic jam-prone interventions on both the A3 and the A40 and will last for several years.” The Leverkusen traffic center also expects traffic jams on the alternative routes in the Duisburg area.
