Construction site on A559 causing massive traffic jams until November 2025!

Traffic chaos in Cologne: Drivers will have to prepare for significant restrictions in traffic flow in the coming months. The construction sites on the A559 cause traffic jams and tests of patience. How news.de reports, the construction work in the Cologne-Gremberg area is a real problem child for commuters and drivers in Cologne.

The first section of the construction work extends from the Cologne-Gremberghoven junction to the Cologne-Gremberg motorway junction in the direction of Cologne-Gremberg. This work has been ongoing since August 18, 2025 and is scheduled to last until September 15, 2025. As part of a new bridge construction, a section of 0.34 km will be renewed, which will also have an impact on the maximum passage width of 7 meters.

Construction work and traffic jams

But that's not all: Further construction phases on the A559 are planned from September 15, 2025 to November 14, 2025. These concern the section from the Cologne-Gremberg motorway junction to the Cologne-Porz exit, with a length of 1.83 km and a maximum passage width of 6 meters. Traffic jams are inevitable here too.

Things will be particularly tricky from November 14th to 17th, 2025: During this period, several important sections of the route will be closed, including the A559 between the AK Köln-Gremberg and the AS Köln-Gremberghoven as well as the A4 and Frankfurter Straße. The construction site lengths add up to 2.67 km and 3.40 km for the A559 and will severely restrict mobility.

Like the traffic jam information service stau.info reported, the current traffic situation is already tense. On September 3, 2025, drivers had to expect up to 2 km of traffic jams between Cologne-Porz and Cologne-Gremberg. Traffic is partially at a standstill between Cologne-Gremberghoven and the Cologne-Gremberg intersection. The construction sites and the high traffic load mean that travel times are significantly longer.

Tips for commuters

For commuters and drivers who rely on the A559, it is now time to remain patient! It's a good idea to plan alternative routes or leave early to beat traffic. The local traffic authorities advise you to regularly check the latest traffic jam and construction site reports in order to stay informed.

The coming months will certainly be challenging. Whether on the way to work or to an important appointment - the construction sites on the A559 will cost everyone involved time and nerves. A look at the traffic situation is therefore essential, as well news.de stated.
