These improvements are part of a broader plan for Brussels’ Ring and surrounding corridors, with potential major traffic disruptions anticipated in multiple zones, including Wemmel, Grimbergen, and along the E40 corridor.

Three nights of maintenance are planned this week on Brussels’ northern ring road (R0) and the E40 toward the capital at Grand-Bigard, with resurfacing and new road markings to be completed in one night per zone.

On the Ring exterior near Wemmel, the 7A ramp from Romaine/Romeinsesteenweg to the R0 will be closed during a Wednesday-to-Thursday night, with traffic diverted via the Jette entrance toward Vilvoorde and a U-turn near Wemmel.

The following night, Thursday-to-Friday, work near Grimbergen spans about 1.3 kilometers between Vilvoorde and Strombeek-Bever; only the left lane remains open and exit 7 (Grimbergen) toward Strombeek-Bever will be closed, with drivers detoured by a U-turn at the Strombeek interchange.

On the E40 toward Brussels, two lanes will be closed Friday night through Saturday at exit 17 (Groot-Bijgaarden/Grand-Bigard) to re-asphalt about 1 kilometer of roadway up to the Brussels region border; eastbound traffic toward the capital will be diverted via the Zellik interchange with a U-turn, then through local roads including Alfons Gossetlaan (N9b) and Nieuwe Gentsesteenweg (N9).

Work begins midweek and runs through the weekend, conducted at night to minimize disruption; existing asphalt will be removed and replaced with a new wearing course, with some ramps temporarily closed and detours in place.
