N14 expressway (Netherlands)

N14, or Rijksweg 14, is a dual carriageway in the province of South Holland in the Netherlands. <br>
It goes from the end of N440 (western interchange with dual carriageway N44, from The Hague city center to motorway A44) and ends in Motorway A4 and the Hague district Leidschenstad. <br>
It is a part of the Ring Den Haag (The Hague), together with local roads, a part of the A4 and the short N440. <br>
In Leidschendam-Voorburg the N14 runs through the three Sijtwende tunnels, which together are just named Sijtwendetunnel "(as if it is just one tunnel!)". These tunnels crosses a railway a local road and a canal, but the longest part runs under residential neighbourhoods, partly alove ground in a "levee".
