Summer work in Amstelveenseweg progressing well

This summer, we are building as many as five new (central) supports for the widening of the viaduct above Amstelveenseweg. The widening is needed for the new lanes on the A10 Zuid. The work is progressing well: the TriAX construction consortium (Besix, Dura Vermeer and Heijmans) has now completed work building the foundations for these new supports. However, the road closure is presenting some challenges, both for the traffic and for the traffic controllers. The first week in particular was somewhat disorganised, because cyclists and public transport were also being diverted. In the meantime, everyone seems to be successfully navigating the situation, although there is still another week to go until Amstelveenseweg reopens on 20 August.

In order to build the foundations, we removed sections of the lanes on Amstelveenseweg around the central reservation. After that, we inserted 38 piles into the ground (on both the north and south side of the viaduct). We poured concrete on the top of these piles, creating a large footing (underground foundation structure). We did this last week for the footing on the north side and are working on the south side this week. When the footings have hardened, we will begin construction work on the new columns. These are made of prefab concrete elements and will have a beam on top of them.

This was not all the work we did. We demolished part of the existing viaduct on the south side to make room for the future widening. We then added a new edge to the existing viaduct. On the east and west side of Amstelveenseweg, we also added a retaining wall structure (next to the embankment). Later this year – after the summer closure is over – we will then be able to dig here and build abutments. These are the foundation structures on either side of a bridge or viaduct. In the years ahead, we will be completing further work on the viaduct after which we will also be regenerating the junction underneath the viaduct.
