The Noorderlijn project makes the north of Antwerp accessible in various ways by tram and metro. The Operaplein will also be transformed into a safer environment for cyclists and pedestrians, with only one tram stop and a parallel road for local traffic at the surface. Underground parking, bicycle storage and the existing pre-metro station will be renovated and expanded. The Rooseveltplaats will also be redesigned to ensure better safety.
The Koningstunnel is a complex structure next to the central station in The Hague, with entrance and exit lanes and differences in the number of lanes per traffic tube and tunnel section. This tunnel also contains as many as 40 technical installations, including lighting, ventilation, traffic detection, etc. In 2019, all obsolete equipment will be replaced and new equipment will be fitted to meet new tunnel safety requirements. The service building will also be modernised and expanded.
