Work on the Bärenkreuzung in the centre of Oberursel started on Monday last week.
Since then, some modifications to the flow of traffic have been made.
It is no longer possible to travel from the Oberhöchstadter Straße across the crossing into the Liebfrauenstraße.
Additional traffic lights have been placed in the Lindenstraße to assist pedestrians.
The one-way system in the Austraße has been reversed so that traffic from the Aumühlenstraße can travel along it back towards the Oberhöchstadter Straße and into the Stadthalle car park.
