Jena, 07.05.2026 – A rear-end collision involving three vehicles caused a brief full closure of the Jagdbergtunnel on the Autobahn 4 on Thursday. No one was injured, and the tunnel was reopened to traffic after approximately half an hour.
- Incident: Rear-end collision involving two trucks and a motorhome
- Location: Autobahn 4, Jagdbergtunnel (direction Dresden)
- Duration: Approximately 30 minutes of full closure
- Consequences: Minor property damage to all vehicles, no injuries
Chain reaction in the tunnel tube
According to current findings, the driver of the leading motorhome had to brake due to traffic conditions. The truck directly behind recognized the situation in time and reduced its speed. However, a second, following truck failed to come to a stop in time. It collided with the truck in front and, due to the force of the impact, pushed it into the motorhome.
Despite the complex situation inside the tunnel, the incident ended mildly. Only minor property damage was caused to all three vehicles. Fortunately, no persons were harmed.
Rapid reopening of the roadway
Due to the police investigation and clearing operations, the tube in the direction of Dresden had to be completely closed for about half an hour. Subsequently, traffic was able to flow again without restrictions, and longer congestions quickly dissipated.
Background: Safety in the Jagdbergtunnel
The approximately three-kilometer-long Jagdbergtunnel south of Jena is a central section of the Autobahn A4. It was put into operation in 2014 to relieve the sensitive Leutratal nature reserve of transit traffic. Due to the closed tube construction, particularly strict safety protocols apply here: even in the case of minor rear-end collisions or broken-down vehicles, the traffic control center often initiates an immediate full closure. This is intended to prevent follow-up accidents within the tunnel structure and to allow emergency services quick, safe access to the accident site.
Experience shows that closures of the tunnel often have an immediate impact on traffic in Jena. Diversion traffic then typically shifts to the Bundesstraße 88 in the Saaletal and places a heavy burden on the junctions in the Lobeda and Göschwitz districts. In this context, the police regularly appeal for the necessity of an early and continuous emergency corridor (Rettungsgasse) on the highway.
