The Belliard Tunnel is currently closed to traffic due to a problem with ventilation.
The tunnel has been closed since 7:30 AM on Tuesday and "technicians are on site," said Camille Thiry, spokesman for Brussels-Mobility to BX1.
As a result of the closure, queues have formed on Belliard and on a section of the ring road.
It is unclear at this time when traffic will return to normal circulation.
