R41 - Aalst


Work on this viaduct was completed in May 2021, finalising the redesign of the Aalst ring road. The new R41 is not only smoother and safer, but can also handle higher volumes of traffic.

Over the past few years, the R41 section between the Kwalestraat junction and Verbrandhofstraat has undergone a complete transformation. Three dangerous intersections were redesigned to include new (bicycle) tunnels that separate local and through traffic. In addition to the tunnels, service roads have also been built. Entry and exit slip roads to the tunnels will be provided between Gentsesteenweg (N9) and Raffelgemstraat. A square has also been laid out on the roof of the Raffelgemstraat tunnel. Roundabouts have been built at the R41/N9 and R41/Raffelgemstraat intersections. The R41/Merestraat intersection was reconstructed at a different location, and once again, bicycle tunnels were added. Gentsesteenweg was redeveloped between Welvaartstraat and Sinte-Annalaan, and wide bicycle paths, new pedestrian pathways, and a separate sewer system were added. The superstructure and substructure of the R41 viaduct between Ledebaan and Verbrandhofstraat were also fully cleaned up and renovated. Sewer systems were fully renovated everywhere, together with all footpaths and street furniture. Finally, we also carried out structural maintenance on the R41between Korte Vooruitzichtstraat and Ledebaan, and between Kwalestraat and Merestraat.
