Accident at Howald Tunnel: the A1 was paralysed by a three-car collision

On Thursday afternoon, traffic on one of Luxembourg's key routes was temporarily paralysed: at around 14:00, three cars collided at the entrance to the Howald Tunnel on the A1 motorway. The accident blocked the overtaking lane, causing a chain reaction of traffic jams towards the Croix de Gasperich junction.

Emergency services and road crews promptly arrived on the scene. According to the authorities, by 15:20 the traffic was partially restored, and the cars involved in the accident were removed from the carriageway.

Although no injuries were reported, the incident again demonstrated how vulnerable key sections of transport infrastructure remain when traffic disruptions occur. The section near Howald Tunnel is traditionally one of the busiest, particularly during daylight hours and when crossing the Gasperich interchange where several directions converge.

While the authorities are working on upgrading road infrastructure and digital solutions for traffic management, such incidents remain a litmus test of the current strain on the system.
