Transmission system operator Thyssengas is carrying out pipeline construction work in Herzogenrath-Merkstein - half-sided closure of Geilenkirchener Straße (L232)

From Monday, 18 August 2025, the transmission system operator will be carrying out maintenance work on a natural gas pipeline in Herzogenrath-Merkstein. This will require the Geilenkirchener Straße (L232) to be closed on one side between the two junctions of the "Am Boscheler Berg" road. Traffic can continue to flow along the construction site and will be regulated by a mobile traffic light system. A speed limit of 30 km/h will be set in the roadworks area for the duration of the works. In addition, the "Am Boscheler Berg" road will only be accessible from the south during the works, and the northern junction with the L232 will be closed. The one-way traffic regulation will be cancelled during this time. The measures are expected to be completed on 19 September 2025.

The work will be carried out in two sections, in each of which one side of the carriageway will be closed. The planning and realisation of the measure will be carried out in close coordination with representatives of the town of Herzogenrath and the responsible authorities. Thyssengas asks for your understanding for the resulting inconvenience.
