Jena, 22.04.2026. Stadtwerke Jena Netze began extensive pipeline construction work in Herderstraße on Wednesday. Due to the modernization of the power grid, there will be a full closure for car traffic in this area until the end of May.
- Measure: Dismantling of overhead lines, laying of underground cables and renewal of street lighting
- Location: Herderstraße (between Westendstraße and Wartburgstraße)
- Period: April 22 to expected end of May 2026
- Traffic: Full closure for vehicles, detour is signposted. Sidewalks are also affected.
Modern underground cables and new street lighting
The focus of the current construction work is an approximately 80-meter-long section of road between the junctions with Westendstraße and Wartburgstraße. Here, an existing overhead power line will be completely dismantled and replaced by cables laid underground. In the course of the necessary civil engineering work, Stadtwerke Jena Netze are also renewing three house connections. After completion of the work, residents will benefit not only from a modern power grid but also from modernized street lighting, which is being brought up to date as part of the project.
For the duration of the measures, it is not possible to drive through Herderstraße in the area mentioned. Drivers are asked to follow the appropriately signposted detour. Pedestrians must also expect temporary restrictions on the sidewalks in the immediate construction area.
Background: Why underground cables are replacing old overhead lines
The gradual dismantling of overhead power lines, as is now the case in Herderstraße, is part of the long-term grid strategy of energy suppliers throughout Germany. Compared to pylons, underground cables are significantly less susceptible to extreme weather events such as strong storms, ice loads or falling trees. This significantly minimizes the risk of local power outages. In addition, the disappearance of the lines visually enhances the public space and reduces maintenance costs for grid operators in the long run.
