• Local Transit Information: Bus Line 16 suspended from July 6 to 19, 2026

  Bus line 16 (Isserstedt – Mühltal – City Center – Ziegenhainer Tal) will be unable to travel through Mühltal or serve the turnaround loop for the duration of the work. Line 16 will therefore be split into a city bus line and a regional bus line.

  • Within the city, Line 16 will operate between Ziegenhainer Tal and the Line 14 terminal stop “Langetal.” The buses will serve all stops along Erfurter Straße. However, trips via Rosental to Cospeda will not be possible. From the Langetal stop, Line 16 continues as Line 14toward Schlegelsberg. In the opposite direction, buses on Line 14 from Langetal become Line 16 toward Ziegenhainer Tal.
  • Regionally, Line 16 runs between Jena Bus Station and Isserstedt, using the route via Jena-Nord and Jägerberg. The stops along Federal Highway 88 cannot be served on this route. At the Isserstedt, Globus stop, there is a connection to shared-ride taxi Line 44.
  • Due to operational reasons, there may be occasional deviations from the regular route as well as changes to the schedules on Line 43 (Bus Station – Flutgraben/Kunitz), Line 47(Bus Station – Lobeda-Ost – Ilmnitz Roundabout), and Line 48(Bus Station – Burgaupark – Maua).
