N11 motorway (Netherlands)

The N11 is a motorway in the Netherlands, connecting Leiden to Alphen aan den Rijn. It is designated as a non-motorway road (Dutch: niet-autosnelweg) despite resembling a motorway in design with grade-separated junctions and two lanes in each direction. The N-designation indicates a national road, managed by Rijkswaterstaat.

The N11 provides a vital link in the Randstad region, alleviating congestion on other east-west routes and improving accessibility to the Green Heart (Dutch: Groene Hart) of the Netherlands. It connects to the A4 motorway near Leiden and terminates near Alphen aan den Rijn, providing access to surrounding towns and cities. The road is important for both local and regional traffic.
