A Dutch aqueduct which goes over a motorway in an incredible feat of engineering has been captured in surreal drone footage which appears to show cars disappearing into the water before they emerge seconds later.
The Veluwemeer Aqueduct in the town of Harderwijk allows boats to sail over the 80ft bridge while cars speed along underneath them.
The remarkable structure was opened in 2002 and connected the mainland of the Netherlands to Flevoland, the largest artificial island in the world.
Drone footage has been captured by Rutger den Hertog, showing the optical illusion as the cars appear to vanish under the water.
The unique underpass is used by around 28,000 cars a day.

The gradient of the Pont du Gard is only 34 cm [a bit over one foot] per km, descending only 17 m [50 feet] vertically in its entire length of 50 km (31 mi)(wiki)
The Dutch one is really just a very short road tunnel: Canal over road.
Canal over canal is much more impressive.
PS: What’s astounding about it today is the total lack of graffiti. ;)
So are you saying the supported load does or does not change with passing boats?
I think the Falkirk Wheel more interesting than any cloverleaf
