00:00:00: Do you realise how lucky you really are? In a moment you will be crossing one of Europe’s largest motorway junctions – with no hint of a traffic jam! Dream on – you drivers down there.

00:00:15: No expense was spared when the Sonnborn junction was built at the end of the sixties. Although it hardly seems possible today, 2,000 people had to move, the monorail’s gantries had to be raised by two metres, and the bed of the River Wupper dropped for almost two kilometres.

00:00:33: And there was even enough money left over to illuminate the entire junction at night. The lights have now been switched off permanently, purportedly to save money. But another reason might be that many of Sonnborn’s inhabitants were sick of seeing this juggernaut day and night.
