Traffic jam alarm in Brunn: closure on the A9 causes traffic chaos!
Traffic disruptions on the A9 between Brunn and Altdorf: construction sites cause closures and traffic jams from June 4th to 5th, 2025.

Traffic jam alarm in Brunn: closure on the A9 causes traffic chaos!
Extensive construction work will begin in Bavaria on June 4, 2025, which will lead to significant traffic restrictions. The affected areas include the Brunn junction on the A9. Loud [news.de](https://www.news.de/auto/858626437/verkehrsmelde-brunn-zur-verkehrsstoerung-wegen-baustelle-sperrung -restrictions-from-04-06-2025-to-05-06-2025-restrictions-in-traffic-danger-of-congestion-in-brunn-zip-code-90475-on-a9/1/) The closure of the junction will last from 10 p.m. to 5 a.m. the following day.
The construction sites cover a length of 2.6 km and affect both the junction and the connecting carriageway. Traffic will be redirected from the Nürnberg-Ost motorway junction (AK) to AK Altdorf, then onto the A3 in the direction of Nuremberg. This change may lead to a noticeable increase in traffic volumes and congestion. The use of traffic guidance systems and adjusted speeds is strongly recommended for drivers.
Additional construction sites and challenges
In addition to the closure in Brunn, a construction site in Haimendorfer Forst (zip code 90552) on the A3 between A3 and A9 is also affected. This measure is also planned for the period from June 4, 2025, 10:00 p.m. to June 5, 2025, 5:00 a.m., with the same diversion route via AK Nürnberg-Ost.
Current reports confirm that the construction site situation is not just limited to the A9. A night construction site on the right and middle lane of the A9 near Schkeuditz, in the direction of Halle/Leipzig, is causing further restrictions, with the exit being closed and traffic being directed to the left lane. This message was updated on June 4, 2025 at 10:22 p.m., as reported by verkehrslage.de.
An additional construction site concerns the transition to the A3 at the Nuremberg junction, which will also be closed on June 4, 2025 from around 10:00 p.m. to 5:00 a.m. Diversions have been set up here to ensure traffic flow.
Road safety and warnings
Drivers should prepare for various hazards that may occur during this construction work. The most common risks include minimal visibility, the risk of slipping due to slippery conditions and stationary and mobile speed measuring systems. There is also the possibility of traffic disruptions due to accidents or obstacles on the road, as listed on verkehrslage.de.
In summary, it is important to observe the announced traffic restrictions and, if necessary, plan alternative routes in order to avoid possible delays. These construction projects are part of ongoing efforts to maintain and improve the road network in Bavaria.
