Jena, July 11, 2026 – Drivers, commuters, and public transport passengers must prepare for new disruptions in the Jena city area during the upcoming 29th calendar week. In addition to new construction sites on Hermann-Löns-Straße and Straße des 17. Juni, ongoing major projects such as those on the Bundesstraße 7 are causing extensive restrictions and schedule changes.
- Period: 29th calendar week (July 13 to July 19, 2026)
- New hotspots: Hermann-Löns-Straße, Schillbachstraße, Straße des 17. Juni
- Major construction sites: Full closure of B7 (Mühltal) and Naumburger Straße (Jena-Nord)
- Public transport restrictions: Bus line 16 interrupted in Mühltal; track work at Paradiesbahnhof
New construction sites and closures from the 29th calendar week
Three new construction projects will begin next week, leading to partial closures and traffic obstructions:
- Hermann-Löns-Straße: At house number 50, a partial closure will be in effect from July 13 to July 17, 2026, due to civil engineering work. Traffic will be regulated by a mobile traffic light.
- Schillbachstraße: On Tuesday, July 14, 2026, the street will be fully closed at house number 11 for crane operations. Between 09:00 and 15:00, the existing one-way street regulation will be temporarily lifted to allow residents to access their properties.
- Straße des 17. Juni: Between Humboldtstraße and Erfurter Straße, a partial closure with traffic light regulation will be in effect from July 13 to August 17, 2026, due to road surface repairs.
Large-scale diversions: B7 and Naumburger Straße
Two large-scale closures require special attention and necessitate extensive detours:
- Bundesstraße 7 (Mühltal): The B7 is fully closed between the Isserstedt roundabout and the Jena city entrance for comprehensive road surface renovation until August 14, 2026. Long-distance traffic is being diverted via the B87, the A4 motorway, and the Jena-Zentrum junction. Local detours are possible via Jägerberg or Rautal. Additionally, access to Cospeda and Münchenroda remains fully closed until July 19, 2026.
- Naumburger Straße (Jena-Nord): Fundamental expansion, including track extension, is underway at the northern city exit. In the first construction phase, which lasts until November 30, 2026, and beyond, Naumburger Straße is fully closed from the city exit to the junction with Carl-Orff-Straße Süd. The long-distance diversion leads from Camburg/Rodameuschel via the L1070 to Trotz and from there via the B7 through Bürgel back to Jena.
Schedule changes in public transport
The closure of the B7 has massive effects on the bus services of the Jenaer Nahverkehrsgesellschaft:
- Bus line 16 (Isserstedt – Mühltal – City Center – Ziegenhainer Tal): This line cannot operate through Mühltal and is split in two. Within the city, buses run between Ziegenhainer Tal and the “Langetal” terminus of line 14. They serve all stops on Erfurter Straße but cannot reach Cospeda. From “Langetal,” line 16 merges directly into line 14. Regionally, buses run between the Jena bus station and Isserstedt via Jena-Nord and Jägerberg. Stops on the B88 are omitted. From Isserstedt (Globus), there is a connection to the on-call taxi line 44.
- Subsequent changes in the bus network: Lines 43, 47, and 48 will experience changed travel times and minor route deviations for operational reasons.
- Track expansion at Paradiesbahnhof: The renewal of the tram line will restrict service until approx. March 31, 2027. The first construction phase is currently underway (until October 15, 2026), during which the track section between Paradiesbrücke and the Paradiesbahnhof stop is closed. This affects lines 1, 4, and 5.
Important information for pedestrians, cyclists, and residents
Some existing closures pose a challenge, particularly for pedestrians and cyclists. For residents and local businesses, the long-term closures are a burden. To support local trade during such construction phases, the campaign “Nimm Platz” for businesses in Jena is running in parallel.
- Forstweg (bridge): Due to the replacement of the bridge between house numbers 12 and 24, the street remains fully closed until December 20, 2026. There is an important exception for pedestrians and cyclists: they may pass the bridge on weekends (from Friday at 14:30 to Monday at 07:00). On weekdays, the signposted detour via Kochstraße, Magdelstieg, and Hornstraße must be used. The municipal utilities warn against entering the construction site on weekdays, as there is significant danger to life in the area of the excavation pit.
- Burgauer Weg: Between Mühlenstraße and the SteinMalEins all-day school, partial closures will occur until presumably the beginning of October 2026. The first construction phase (until August 16) affects the area between the school and the turn-off to the boathouses, with limited parking available at the school.
- OBI-Tunnel: The pedestrian and cycle path from the OBI-Tunnel to Camburger Straße is fully closed until August 14, 2026, due to expansion work. The detour is via the Saalbahnhof-Tunnel.
🚗 Traffic & everyday consequences of the construction wave
The simultaneous renovation of major traffic arteries such as the Bundesstraße 7 and Naumburger Straße is putting the Jena traffic network to the test. Commuters from the Weimarer Land and northern Thuringia must plan for significant extra travel time. Since inner-city hubs like Paradiesbahnhof are also affected by track reconstruction, Jenaer Nahverkehr recommends checking the connection information daily before starting a journey. Especially the small-scale alternative routes via Rautal and Jägerberg regularly reach their capacity limits during peak hours, which is why long-distance detours via the A4 motorway are urgently recommended.
