During this time, the intersection at quai de Willebroek and Petite Ceinture will be temporarily closed, with traffic diverted through underground tunnels or alternative surface routes such as quai de Willebroek, place des Armateurs, and avenue du Port.

Major construction projects in Brussels this autumn are set to cause significant disruptions across transportation networks, including tram, bus, and cycling routes.

One of the key projects involves renewing tram rails along Yser, leading to the closure of the surface section of Petite Ceinture towards Basilique from October 20 to November 1, coinciding with the autumn holidays.

As a result, tram line 51 has already been interrupted, and bus routes operated by De Lijn will be diverted during this period.

At Place Sainctelette and Place de l'Yser, major work will take place from October 20 to November 1, including tram rail renewal and infrastructure improvements to better distribute traffic among different modes of transportation.

During this project, the access ramp from Avenue des Communautés to E40 will be closed on October 25 and 26, with a detour via Louvain road, and cyclists will need to use alternative routes such as Gulledelle and Reyers.

These projects are part of broader efforts to enhance Brussels' infrastructure, but they are expected to cause considerable disruptions to transportation during the autumn period.

Additionally, the Ring road at Carrefour Léonard will be completely closed for two hours to facilitate construction activities, though the specific date has not been announced.

Starting October 27, the cycling lane along the E40 highway between Avenue des Communautés and Colonel Bourg will undergo redevelopment, including creating a green median and resurfacing with asphalt to improve safety and comfort.
