N12 reopens in Bassonia after deadly tanker blaze shuts major Joburg route
Johannesburg motorists waking up to a new week have at least one headache off the list. The N12 in Bassonia is officially open again after a deadly collision and gas tanker fire shut down one of the south’s major freeway routes over the weekend.
For many drivers in the southern suburbs, the closure was more than just a traffic delay. It turned a key stretch of road into a no-go zone and pushed pressure onto surrounding routes while emergency teams dealt with a scene that was anything but routine.
A dangerous job behind the scenes
According to the Johannesburg Metropolitan Police Department, the freeway has reopened in both directions after teams completed a high-risk decanting process and extensive clean-up work following the incident on Sunday, 19 April 2026.
That matters because this was not a standard crash recovery. The incident involved a gas tanker, which meant emergency crews had to move carefully and treat the area as hazardous before the road could be handed back to the public. In a city used to road closures for collisions, this was the kind of situation that demanded specialised handling and patience from everyone around it.
Authorities have now declared the roadway safe for public use. Diversions that had been in place at the R59 Reading Interchange and Comaro Road have also been lifted.
A weekend closure felt across the south
Anyone travelling through Bassonia, Comaro, Glenvista, and nearby parts of southern Joburg would have felt the knock-on effect. When a major arterial route, such as the N12, closes, traffic pressure quickly spills into suburban roads, and that ripple can last long after the flames are out.
This time, the disruption came with an added sense of urgency. The cargo was hazardous, the fire risk was serious, and the response had to prioritise safety before speed. It is the sort of reminder Joburg gets too often: one major incident on a key route can reshape movement across a whole section of the city.
Relief, but also a sobering reminder
JMPD thanked emergency personnel who worked in dangerous conditions to stabilise the scene and restore traffic flow. The department also thanked motorists and residents for their patience during the closure.
There is relief in the reopening, of course, but it comes with a heavy note. The crash was fatal, and that fact should not get lost in the rush back to normal traffic updates and Monday commutes.
On social media, much of the reaction around the incident centred on concern, shock, and frustration over the closure, followed by relief once the reopening was confirmed. That public response says a lot about life in Johannesburg. Roads here are not just roads. They shape workdays, school runs, deliveries, family plans, and the daily rhythm of the city.

Back open, but not forgotten
Now that the N12 is open again, traffic in the area is expected to normalise. But the incident will likely stay in the minds of many commuters who saw the alerts, sat through the diversions, or live close enough to Bassonia to feel the disruption firsthand.
For Joburg, this was one of those stories that started as a traffic warning and ended as something bigger: a reminder of how fragile the city’s flow can be and how much depends on the people who step in when things go wrong.
