To ensure that the old and dilapidated motorway viaduct on the A4, which runs over the L136 local road, survives until next year, a support girdle has been built on the L136, which has been closed since March for this reason. Now, the final stage of the works is starting.
“The construction must be completely free of vibrations and shocks, and this requires the complete closure of the A4 motorway,” explains German motorway operator Autobahn GmbH. Detours have already been set for long-distance traffic.
Closure times and diversions
From Friday, 12 July at 22:00 to Monday, 15 July at 05:00, and the following weekend – from Friday, 19 July at 22:00 to Monday, 22 July at 05:00 – the A4 between Bergisch Gladbach – Bensberg Junction and Overath-Untereschbach Junction will be completely closed in both directions.
As a result, drivers in local traffic heading towards Opel will have to exit the motorway at the Bensberg junction. A diversion for those travelling towards Cologne will start at the Untereschbach interchange.
Diversions for long-distance traffic
Direction Cologne
Drivers travelling towards Cologne/western North Rhine-Westphalia are already being directed to a diversion at the Bielstein junction. This leads via the B56, L189, as well as the B507 (Jabachstrasse) and B56 (Zeithstrasse) to the A3-AS Lohmar motorway.
Direction Olpe
Before the Heumar junction (A3/A4) and before the Cologne-Ost junction (A3), messages displayed on screens above the motorway indicate that the A4 motorway is completely closed. Drivers heading towards Olpe/Oberbergischer Kreis are being diverted via the A3 motorway towards Frankfurt to the Rösrath interchange and then onto the L288 (Sülztalstraße) and the B484 to the A4, Overath interchange.
