Jena, June 28, 2026. Tomorrow, Monday, June 29, 2026, one of Jena’s most important traffic hubs will transform into a major construction site: the fundamental expansion of the tram tracks begins around Paradiesbahnhof. Passengers, pedestrians, cyclists, and drivers must prepare for significant restrictions, closures, and extensive detours in the inner-city area.
- Project: Fundamental renewal of 610 meters of tracks, six switches, and three track crossings, as well as the barrier-free conversion of the Paradiesbahnhof stop.
- Construction Period: Starting Monday, June 29, 2026. First phase until mid-October 2026. Overall completion in April 2027.
- Mainly Affected: Tram commuters, cyclists, and pedestrians in the center, as well as road traffic around Knebelstraße.
- Connection Tip: Use the designated detours and plan for additional travel time, especially during rush hour.
Necessity of Renovation after 30 Years of Operation
The rail tracks around the busy track triangle at Knebelstraße largely date back to the 1990s. After around three decades of intensive use by local public transport and crossing individual traffic, the track facilities show significant signs of wear. To ensure safe and reliable tram operations for the coming decades, Jenaer Nahverkehr is now carrying out these extensive renovation works. In the course of the measures, the Paradiesbahnhof stop will also be completely redesigned to be barrier-free.
This major construction site requires a logistical masterpiece, as it corresponds in time with other urban infrastructure projects – such as the planned large district heating interruption starting June 30, which also requires temporary adjustments in the city area.
Detailed Schedule of Construction Phases
The overall project is divided into several sections to stagger the restrictions in the city center as much as possible:
- Phase 1 (June 29 to mid-October 2026): Closure of the track triangle at Knebelstraße. During this time, the most intensive track construction work and the replacement of the switch connections will take place.
- Phase 2 & 3 (mid-October 2026 to April 2027): Completion of the track areas, connection work to the existing infrastructure, and the full barrier-free expansion of the stop facilities at Paradiesbahnhof.
Specific Closures at the Traffic Hub
From Monday morning, the following construction-related closures will take effect in the construction area:
- Track Closure: Tram traffic between the city center (Holzmarkt) and the southern districts via Knebelstraße is completely interrupted.
- Lane Restrictions: On Knebelstraße, there will be narrowing and closures of individual lanes for motorized individual traffic in the construction area.
- Footpath and Cycle Path Closure: The direct footpaths and cycle paths along the construction site at the Volksbad and on the Paradiesbrücke are closed in sections.
Detours for Commuters, Cyclists, and Pedestrians
To manage traffic flows, comprehensive detour concepts have been developed to maintain traffic flow as best as possible:
- Tram Traffic: The routing will be fundamentally adjusted during the first phase. Trams from the north will end in the city center, while a rail replacement service (SEV) with buses will be established for the routes towards Lobeda and Winzerla. Exact schedule changes can be found on the notices and the digital information media of Jenaer Nahverkehr.
- Pedestrian Guidance: Pedestrians wishing to reach Paradiesbahnhof or the adjacent Volksbad will be guided around the construction field via secured and signposted alternative routes.
- Cycle Traffic: Cycle traffic will be diverted over a wide area via the paths of the adjacent Paradiespark and the Rasenmühleninsel to avoid conflicts in the narrow construction area at Knebelstraße.
🚗 Traffic & Everyday Consequences: Paradiesbahnhof as a Lifeline
The area around Paradiesbahnhof is considered one of the most heavily frequented sections of Jena’s transport network. Here, not only the most important north-south tram lines of the university city connect, but also regional rail traffic on the Saalbahn with urban and regional bus traffic. Knebelstraße also serves as an important connecting axis to the B88 federal highway. Due to this enormous strategic importance, construction work at this bottleneck has an immediate impact on tens of thousands of commuters from the entire city area and the surrounding region. The use of alternative routes via the western and eastern bypasses is strongly recommended during peak traffic hours.
