Iserlohn begins ground stabilization for road redesign

The city of Iserlohn is undertaking extensive ground stabilization work to facilitate the redesign of the Theodor-Heuss-Ring. The infrastructure project aims to install two new roundabouts at the intersections of ‘An der Isenburg’ and ‘Sofienstraße’. This redesign is intended to reduce turning lanes, create more space for pedestrians and cyclists, and calm traffic to improve access to the Schillerplatz area.

Due to historical mining activities, the city must address underground risks. A significant focus is the ‘Schacht von Hövel’ on Mendener Straße, a shaft discovered to be 206 meters deep. Recent drilling confirmed the presence of unstable, soft material and loose stones within the shaft. To ensure long-term ground stability, the city is preparing a tender to have a specialist company fill the shaft with construction material. These operations are expected to last several months and may continue into early 2027.

Additionally, exploratory drilling is being conducted at a test shaft near the town hall. These investigations, carried out by Keller GmbH and expert Dr. Spang, have identified soft zones that require attention to ensure the safety of the planned road construction.
