Control of Willemsspoortunnel to a higher level

Yunex Traffic is renewing the control system of the tunnel technical installations (TTI) in the Willemsspoortunnel on behalf of ProRail. A new stationary train detection system is also being implemented. The project takes the availability, safety and efficiency of the rail tunnel to a higher level.

Piet Hein tunnel renovated and open for traffic again

The Piet Hein tunnel has been reopened at the end of January 2023. The tunnel was closed for nearly nineteen months for renovations. At that time, an alliance between the municipality of Amsterdam, Yunex Traffic and Heijmans lifted it to a higher level. The Piet Hein tunnel was opened in 1997 and is a main artery of the Amsterdam road network. About 30,000 vehicles drive through it every day. The renovation fell within the program ‘Approach Road Tunnels Amsterdam’ (AWA). Existing installations and systems in the tunnel and the control system have been completely renewed and expanded. Major maintenance has also been carried out on the civil and structural parts.

High-tech central control for weir ensemble Nederrijn and Lek

The renovated Nederrijn en Lek barrage ensemble was completed at the end of December 2020. The weirs and locks in Driel, Hagestein and Amerongen can continue to perform their tasks safely and reliably in the coming decades. Rijkswaterstaat awarded the Design & Construct contract to Yunex Traffic as main contractor within a consortium with Soldidd Steel Structures for steel construction and DEME Infra for hydraulic engineering work.

Amsterdam metro network ready for the future

In alliance form, the Amsterdam Metro and Tram (MET), Municipal Transport Company Amsterdam (GVB) and Yunex Traffic have prepared the Amsterdam metro network for the future.
The North/South line was opened in Amsterdam in July 2018, for which Yunex Traffic realized the central control installation (CBI) and the station systems. Subsequently, the existing metro network was modernized and integrated into the CBI of the North/South line.
All stations are now linked to the central operating, monitoring and control installation of the North/South line. As a result, the operators of the Amsterdam metro network no longer have to work with different platforms. This is simpler, increases the overview, prevents errors and thus contributes to safe and trouble-free metro traffic.


After intensive maintenance on various Delta Works, the Netherlands entered the storm season with a safe feeling. The sensors on the Oosterscheldekering between Schouwen-Duiveland and Noord-Beverland have been renewed, among other things, which ensure that the gates lower evenly when the barrier is closed. Jos Maassen of Rijkswaterstaat (RWS) and Andy Kriek of Yunex Traffic talk about this project.


Talking Bikes

Cycling is healthy and good for the environment. In order to create optimal infrastructure and mobility solutions for cyclists, governments need insight into our cycling behaviour. In collaboration with Tracefy, Yunex Traffic helps municipalities and provinces to make the right choices by enriching bicycle and ride data into useful information.

Hollandsche Ijsselkering

Successful migration on Hollandsche IJsselkering

In 1958, the Hollandsche IJsselkering was the first of 13 Delta Works to be put into operation. It consists of two barriers, a lock and a bridge. In 2011 Yunex was commissioned by Rijkswaterstaat to migrate the hardware and software of the Hollandsche IJssel storm surge barrier. All network components have also been replaced and the cyber security has been adjusted in accordance with the wishes of Rijkswaterstaat. We successfully carried out this project together with Rijkswaterstaat. Commissioning went smoothly. Yunex Traffic is responsible for maintenance for 7 years after delivery.
