To divert the cycle path, a partial closure of the southern carriageway (towards Freienohl) is necessary. Traffic can continue to flow past the construction site and is regulated by a mobile traffic light system
. Cyclists will be diverted.

Utility works in Im Neyl, near the Ruhr Bridge
Utility line works are also taking place in the area of house number 2, near the Ruhr Bridge.

About the Ruhrtal Pipeline project
Due to increased capacity requirements, Thyssengas GmbH has been expanding its gas transmission system in the Wickede / Arnsberg / Meschede region – known as the Ruhrtal pipeline – since 2018. The existing pipeline system is being renewed in several construction phases, and transport capacity is being increased as part of this work. The Ruhrtal pipeline supplies gas to the downstream networks of the local municipal utilities as well as to numerous large-scale customers such as industrial plants and power stations. Completion of the entire project is scheduled for 2027.
