The three tunnels are being closed to allow works to proceed connected to Schuman Station in the European District.
Motorists driving out of the European capital or people using public transport should not experience any problems.
The Belgian automobile association Touring is incensed by the way motorists are being treated. Touring's Danny Smagghe: 'Drivers are being placed in front of a fait accompli.'
The motorists' association is particularly upset about the communication with drivers: "Three important tunnels are being closed. At the same time part of the Leuvensesteenweg is being made car-free and there are works at the important Kunst-Wet intersection. This is bad news for mobility in Brussels."
