Closure of the A8: Neunkirchen-Oberstadt affected until September 2025!
On May 28, 2025, there was another significant change on the A8 motorway towards Luxembourg. Extensive construction work will begin on Monday, June 2, 2025, which will affect the Neunkirchen-Oberstadt exit until the end of September 2025. This emerges from a statement from the West branch of Autobahn GmbH. The reason for the closure is the comprehensive renovation of the exit button, which will inevitably lead to traffic restrictions.
The closed exit will be completely inaccessible until the fall. Road users must therefore prepare for a diversion. This will be routed via the subsequent Neunkirchen-Spiesen junction, with clear signage guiding drivers to the alternative routes. However, the notice from Autobahn GmbH warns of possible disruptions, even if the work is carried out during off-peak times.
Details about the full closure
In addition, the road towards Pirmasens will be completely closed between the Neunkirchen-Oberstadt (24) and Wellesweiler (25) junctions. However, this measure is subject to suitable weather conditions. A local diversion will be set up to direct drivers from the Neunkirchen-Oberstadt junction via the L114 and Zweibrücker/Limbacher Straße through Furpach. From there you continue to the Neunkirchen-Kohlhof junction (26) to get back onto the A8.
Road users should prepare for possible disruptions on one of the affected weekends. It is recommended that you pay attention to radio reports and take possible disruptions into account when planning your route. It is also advisable to plan a reasonable travel time for the diversion route to avoid delays.
Recommendations for drivers
Autobahn GmbH asks that you drive carefully and understand the traffic disruptions that will arise as a result of this necessary work. In order to maintain traffic, it is recommended to follow the latest traffic reports on the radio, especially on June 2nd and in the following months, and to consider alternative routes if necessary.
