Editing Route number (section)

====Netherlands' A, N system====
A stands for "Autosnelweg" (motorway), N for '''N'''on motorways. The A-codes use white letters on a red shield, the N-codes black letters on a yellow shield. Where a highway changes into a motorway or vice versa, it may continue to use the same number, but the letter and the color are switched.<br />
When the letter is followed by three digits, the road is typically a provincial road. When there are only one or two digits, it is typically a national road.
