Jena, May 29, 2026. At the beginning of June, drivers and commuters in and around Jena must prepare for significant traffic disruptions. Three important traffic axes – the state road L 2308, the district road K 12, and the busy Löbdergraben – will be temporarily fully closed due to renovation work and a crane placement.
- What: Three full closures in the Jena city area and surroundings (L 2308, K 12, Löbdergraben)
- Periods: June 1 to June 5, 2026 (L 2308), June 2 to July 10, 2026 (K 12), June 1 (05:00 a.m.) to June 4, 2026 (08:00 p.m.) (Löbdergraben)
- Affected routes: Jena-Ammerbach to Nennsdorf, Closewitz to Cospeda, Löbdergraben (southbound)
- Detours: Signposted routes or via Lützeroda and Lutherplatz/Am Anger/Am Eisenbahndamm
Full Closure of the L 2308 between Ammerbach and Nennsdorf
The state road L 2308 will be fully closed in the section between Ammerbach and Nennsdorf. The reason for the measure is an urgently needed renovation of the road surface.
- Period of closure: Monday, June 1, 2026, until presumably Friday, June 5, 2026.
- Detour recommendation: A corresponding detour for through traffic will be officially and clearly signposted on-site.
Renovation Work on the K 12 between Closewitz and Cospeda
Significant restrictions for vehicle traffic will also occur in the northern surroundings of Jena. A comprehensive surface renovation is starting on the district road K 12 between Closewitz and Cospeda. This construction measure makes a full closure unavoidable. It should be noted that the hiking parking lot located along the route will also be inaccessible to visitors and hikers during the entire construction period.
- Period of closure: Beginning on Tuesday, June 2, 2026, until presumably Friday, July 10, 2026.
- Detour recommendation: Traffic will be officially detoured in both directions via the nearby village of Lützeroda.
Crane Placement at Löbdergraben Closes Southbound Direction
Directly in Jena city center, road users must also prepare for significant restrictions. A large construction crane will be erected at Löbdergraben in the southbound direction – in the section between Fürstengraben and Saalstraße. For the duration of this work, the roadway must be completely closed.
- Period of closure: From Monday, June 1, 2026, starting at 05:00 a.m., until Thursday, June 4, 2026, at approximately 08:00 p.m.
- Detour recommendation: The inner-city bypass of the closure for motor vehicles will be routed over a wide area via Lutherplatz, the street Am Anger, and Am Eisenbahndamm.
Road users are urgently requested to bypass the affected areas as much as possible and to plan for additional travel time, especially during peak commuting hours.
