Will the whole of the Brussels Ring Road be changed immediately?

The changes are happening in the northern section of the Brussels Ring Road between the E40 (direction Ghent) and the E40 (direction Leuven). That section will be split into three zones: the Zaventem zone (from the junction with the E40, direction Leuven, up to and including the junction with the E19 to Antwerp), the Vilvoorde zone (from the Vilvoorde viaduct to the junction of the A12 in Strombeek-Bever) and the Wemmel zone (from the junction of the A12 in Strombeek-Bever to the junction of the E40 in Groot-Bijgaarden).
