The accident on the anti-clockwise section at Jette had commuters stuck in traffic for up to three hours.
Three cars were involved in a smash in Jette at 7:15 this morning. Nobody was hurt but the fast and central lanes had to be closed.
Jams tailed back from Jette all the way to Braine-l'Alleud (Eigenbrakel) covering a distance of 40 kilometres. Drivers on the clockwise section slowed down too in a bid to see what is happening on the other side of the motorway. This also delayied traffic.
Because of the chaos on the motorway other entry roads into Brussels were affected too.
The carriageway is now be clear, but a spokesman for the Traffic Information Centre warned drivers to avoid the ring as much as possible on Tuesday morning.
