Jena, 12.04.2026 – Anyone traveling in the south of Jena will need to plan for a bit more time in the coming weeks. Due to urgently needed surface renovation, the entrances and exits of the Gewerbegebiet Maua will be fully closed in sections starting Monday, April 13, 2026.
- Measure: Full closure of entrances and exits (Gewerbegebiet Maua)
- Reason: Surface renovation of the roadway
- Phase 1 (Direction Rudolstadt): April 13 to approximately April 24, 2026
- Phase 2 (Direction Jena): April 27 to approximately May 8, 2026
- Detour: Signposted via the Maua roundabout and the Rothenstein exit
Two Construction Phases for Roadway Renewal
To keep disruptions to the flow of traffic as low as possible, the renovation work has been divided into two temporal construction phases. In the first phase, the closure exclusively affects road users traveling on the federal highway in the direction of Rudolstadt. From April 13 to approximately April 24, 2026, entering and exiting on the eastern side of the industrial estate will not be possible.
Following a changeover during the weekend, the second phase begins on April 27, 2026. Until approximately May 8, 2026, drivers must then expect the full closure of the junctions in the direction of Jena. A corresponding detour route has been established for the entire construction period, directing traffic via a U-turn at the Maua roundabout or via the nearby exit in Rothenstein back onto the planned route.
Background: A Bottleneck for Commuters and Logistics
The directly adjacent Bundesstraße 88 forms one of the most important traffic axes in southern Jena. It connects the university city with the Saale-Holzland-Kreis and the Saalfeld-Rudolstadt region. The Gewerbegebiet Maua is not only an essential economic location for local companies but also steadily attracts customer traffic through retail. Especially during morning and evening rush hours, increased congestion is to be expected at the main junctions – particularly at the Maua roundabout and the Rothenstein traffic light intersection. Drivers are advised to plan for additional travel time during peak hours.
Further Restrictions: Lobeda-Ost and Autobahn 4
In addition to the work in the Gewerbegebiet Maua, other infrastructure projects are starting in parallel, which will selectively impact Jena’s traffic. Also on Monday, April 13, 2026, construction work on the tram network will begin, interrupting rail traffic to Lobeda-Ost. The transport companies are setting up a rail replacement service.
A major project is also casting its shadow on the Autobahn 4: From mid-May 2026 until approximately December 2027, an extensive renewal of the roadway will be carried out between the Jena-Zentrum junctions and the adjacent areas. This may lead to significant restrictions on the east-west axis.
