In the coming years, the Holland Rijnland region will invest in maintaining and strengthening its position in the Randstad, for example by improving accessibility and growth of the housing supply. Without the RijnlandRoute – a new connection between the A4 and Katwijk – the developments will lead to an increase in traffic on the existing road network, which is already under pressure. Spatial integration of the RijnlandRoute is a complex task, for which an Aesthetic Program of Requirements has been drawn up. The provincial road will be intertwined with the existing national highways A4 and A44 and constructed in very vulnerable landscapes and densely built-up areas around Leiden. The road design is therefore reserved and subordinate to the landscape.
