Nationale Wegen (National Highways) or simply N-wegen (N-roads), was a numbering system for a set of main highway routes in the Netherlands, used from 1957 through 1976.
In 1957, signposted road numbering was introduced in the Netherlands and the governments Rijkswegen plan foresaw in an increasing number of highways, together forming a nationwide system. Alongside the pan-European E-road numbers, which were given to routes of international importance, a complementing series of N-road numbers was devised to designate those routes not included in the European system, but considered of national significance.
In 1976, the until then administrative only Rijksweg numbers were adopted as the new road denominations, along with a completely new series of N-numbers for Non motorway highways, in 1978. The original brown N-numbers on road-signs were since then replaced with red A-numbers, for Dutch motorways, and new yellow N-numbers for other highways. The E-road system was significantly renumbered in 1985, but remains signposted everywhere in the Netherlands.
For this road system the numbers 89 to 100 were used. This is because the numbers leading up to 85 were used for the original Rijksstraatwegen and later the modern rijkswegen count.
