As you may recall, at the end of September 2025 almost half a million kilogrammes of concrete reached our construction site on the river Schinkel. We brought three gigantic bearer beams ashore after a four-day canal journey that you could watch live via an on-board webcam. The beams are a key component of the new 300 m long flyover that will connect the A10 Zuid to the A4. The TriAX construction consortium (Besix, Dura Vermeer and Heijmans) is fitting the beams on top of the columns on which the road surface will ultimately rest. The first two bearer beams – currently in storage on our work site in Riekerweg – are being put in place on top of the two (most easterly) column next to Joy tennis club on Tuesday, 14 October.
Just under the bridge
We are transporting the two beams from the construction site in Riekerweg on a special trailer designed to carry a very heavy load and pulled by a vehicle. This will be moving gradually in the direction of Anthony Fokkerweg via Vliegtuigstraat (construction route 1, see map).
Transporting them is similar to the process of bringing the bearer beams ashore. They only just fit under the Schinkelbrug bridge and their size means they cannot be rotated by 180°. Their transportation is therefore a very intricate process (involving some very slow driving). The time-lapse video below provides a good impression of how things went when we brought them ashore from the pontoon on 26 September.
Every millimetre matters
On arrival at the columns, we will hoist the bearer beams upwards using two cranes. As soon as a beam is (hanging) in the right position, we will place a bracket between the column and the bearer beam. This will then be lowered until the beam is safely in position. This is precision work where every millimetre matters. Fitting the first beam is expected to take as long as two hours. We are assuming that the second beam will be in position slightly more quickly.
Closure of A10 Zuid 7-10 November 2025
We are able to fit the two bearer beams in place without closing the A10 Zuid. This will not be possible for the other seven bearer beams for the flyover (which will be travelling to Amsterdam in different convoys in the upcoming period). In the weekend from 7 to 10 November 2025, we will be fitting two more onto the columns and another one on the night of 13/14 December. We will provide regular updates – keep an eye on our website. The last four bearer beams will be fitted in 2026. The flyover will be ready in 2028.
Widening of A10 Zuid
The flyover is part of the reconstruction of the De Nieuwe Meer junction that is needed in order to widen the A10 Zuid by adding two extra lanes for local traffic. In the future, traffic will either leave the city from the S108/Amstelveenseweg or take the S109/Europaboulevard to reach the new parallel carriageway. Drivers will then be able to take the new flyover from the De Nieuwe Meer junction to reach the A4 Schiphol/Rotterdam.
