Historical Background and Development of Prins Clausplein
Early Motorway Development and the Origins of Prins Clausplein
Prins Clausplein’s story begins with the dawn of Dutch motorway infrastructure. In 1937, the Netherlands opened its first motorway, the A12, spanning nine kilometers between Voorburg and Zoetermeer. This milestone marked the start of the Dutch motorway network (cultureelerfgoed.nl). Subsequent decades saw the A12 extended to Gouda and the late-1950s opening of the A4, with their intersection becoming a major regional traffic node as The Hague’s importance grew.
The Leidschendam Roundabout and the Need for Modernization
Before Prins Clausplein, the Leidschendam roundabout handled traffic at this location. By the 1970s and 1980s, increasing vehicle volumes led to severe congestion and delays, revealing the need for a more advanced solution. The inefficiency of the roundabout propelled plans for a modern, high-capacity interchange (cultureelerfgoed.nl).
Design and Construction of Prins Clausplein
To address these challenges, the Dutch government commissioned the construction of Prins Clausplein, which opened in 1985. The interchange replaced the Leidschendam roundabout and became a critical node for the A4 and A12. Featuring a rare “Malthezer kruis” (Maltese Cross) design, it is the only four-level, grade-separated motorway junction of its kind in the Netherlands. The A12 runs at the lowest level, the A4 above it, and two sets of flyovers on the upper levels enable direct connections between major cities (cultureelerfgoed.nl; Reddit).
The structure stands as a visual and engineering landmark, frequently referenced in discussions on infrastructure as urban art (TU Delft Repository).

Integration with Rail and Urban Networks
The Den Haag–Utrecht railway line crosses Prins Clausplein’s southwest side, highlighting its role as a multimodal hub. The integration of road and rail required complex planning to ensure safety and efficiency (cultureelerfgoed.nl). Additionally, in 1998, “vlechtwerken” (braided connections) were constructed between Prins Clausplein and the adjacent Ypenburg interchange to reduce weaving and improve traffic flow. At the same time, the A4 was widened to ten lanes, reflecting growing mobility demands.

This solution, proposed by local resident Henk Sijsling, is commemorated with a road sign (cultureelerfgoed.nl).
