New connection between A10 Zuid and A4 almost complete

The flyover is a 300-metre-long, 14.5-metre-wide connecting road supported by nine enormous concrete pillars. These are spread across the northern side of the De Nieuwe Meer junction and rise as much as 9.5 metres above the ground. The road itself consists of 120 concrete girders, each around 30 metres long and weighing 45,000 kilograms – the equivalent of 30 passenger cars or 75 adult horses. A layer of concrete is poured over the girders to bind them together into a single structure, on which the asphalt will eventually be laid. Once all the girders are in place, they will form ten groups of twelve, laid end to end across the junction and supported by the pillars – as shown in the illustration below.

We began lifting the girders into place in mid-December 2025, working one construction weekend at a time. This set a carefully coordinated sequence of work in motion. During the first weekend, we lifted the girders into position between the abutment and pillars 10 and 9 (see illustration). The following construction weekend, we poured a concrete topping layer over those girders and installed the next set of girders on the following two pillars. And so the work continued, weekend after weekend, bringing us to the current stage: lifting the girders into place between pillar 2 and the abutment on the western side of the junction.

Before installing the final twelve girders, we had to wait until the ground around the abutment at the end of the flyover was sufficiently stable. That is now the case, so we can lift the remaining girders into position at the end of November. Early in the new year, we will pour the concrete topping layer over the final two spans – the sections between pillar 3 and the abutment. In early April 2027, we will lay the asphalt across the entire flyover. Finally, we will add the road markings and install the road signs and overhead electronic traffic signs. The flyover is scheduled to open to traffic after summer 2027.
