Mosseveien closes after EV fire, Oslo artery stalls on single crash, detours push traffic inland

• VG reports that Mosseveien was closed after an electric car caught fire following a crash near Ljan in Oslo.
• Fire crews said extinguishing the vehicle would take time, extending the closure of a major route between the southern districts and central Oslo.
• The disruption shifts traffic onto inland alternatives, where a single closure can quickly spill into commuter congestion.

An electric car caught fire after a crash on Mosseveien near Ljan on Friday, forcing police and fire crews to shut one of Oslo’s main southern approach roads. VG reports that the road will remain closed while firefighters work on the vehicle, and that crews expect the extinguishing operation to take time.

The immediate incident is small: one vehicle, one stretch of road, one closure. The effect is larger because Mosseveien is not a side street but a coastal corridor feeding traffic from the southern parts of Oslo toward the city centre. When that route closes at Ljan, drivers are pushed onto inland roads and local alternatives that were not built to absorb much slack. A single crash is enough to turn the morning or afternoon commute into a queue that spreads well beyond the accident site.

Electric-vehicle fires add an operational problem that ordinary collision reports often skip. Fire services have repeatedly said battery fires can demand longer cooling, monitoring and re-ignition control than a conventional engine fire, which means the road can stay blocked well after the crash itself is over. VG’s report points in that direction here: the key detail was not only that the car burned, but that crews expected the job to take time. For motorists, the distinction matters less than the result. A road that carries heavy commuter traffic is either open or it is not.

That leaves Oslo with the familiar geometry of a constrained capital: fjord on one side, steep terrain on the other, and a few heavily used corridors tying the southern districts to the centre. The detour map is short. Once traffic is diverted away from Mosseveien, pressure moves inland toward other arterial roads and residential approaches, where delay compounds quickly. The city’s transport system can absorb routine volume; it has less room for interruption.

Friday’s closure was caused by a single burned car near Ljan. The fire brigade’s estimate was simple: the road stays shut for as long as the battery keeps them there.
