The road connects the capital city of Amsterdam, near the interchange of Watergraafsmeer, with the German border, near Oldenzaal and Bad Bentheim, and the German Autobahn BAB 30.
On its way, it crosses four provinces: North Holland, Utrecht, Gelderland and Overijssel.
Between the interchange Hoevelaken and the German border (and beyond, along the BAB 30), the European route E30 follows the A1 motorway.
This European route is a so-called A-Class West-East European route, going from Cork in Ireland all the way to Omsk in Russia.
