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.

If we ever go to another planet snd need specialists in terraforming we should call the Dutch.

Just shaking my head. One of the comments: “Good old American Ingenuity.”
It was built by the Dutch. In The Netherlands. In 2002.
Tell me what any of that has to do with American Ingenuity?
The Unfrozen Caveman Lawyer might think such...as he drives his BMW with the windows up.
daily mail comments are good for a laugh many times.
I read a few weeks ago that they were Sold, I hope the New owners as as great as the old owners.
not sure why they just didn’t build a small bridge.....w/e....
Reminds me of the taxiway at the old Denver Stapleton Airport. There was nothing weirder than driving on I-70 and seeing a huge jet taxiing ABOVE you.
I think the caption writer needs a refresher in physics: “ The aqueduct is made up of 22,000 cubic meters of concrete to support the weight of the water and boats above the motorway below.” Does the supported weight change when there is a boat directly overhead?
Reminds me of the old story of the truck driver banging on his cargo trailer to get the canaries flying so he could safely cross the bridge.
Mitchell Intl in Milwaukee has one runway going over a 4-lane road.
Drone footage - nope, tried to visualize/see the optical illusion but didn’t.
Wow, maybe they can finance it using Bitcoin bonds
Yeah. We would build 20 giant project housing units for those who live the lifestyle on the take, demolish in 15-20 years and rebuild. Repeat and graft in the the NUSA.
Lock/elevators are as good as you can get until water flows uphill
Walt Disney in Fla did it in the 70s.
“Does the supported weight change when there is a boat directly overhead?”
Archimedes has the answers you seek. A boat floats by definition because it is displacing an equal amount of water vs the total weight of the boat. I say weight and not mass as weight is mass plus gravity which is the actual physics component governing displacement in earth’s gravitational field. A boat of equal mass would float higher in the water and displace less fluid on the moon due to the moon having one quarter the gravitational pull of earth.
“not sure why they just didn’t build a small bridge”
Boats such as sailboats are taller than vehicles. Great to have the boats on top.
That trailing powerboat seemed to be happy to get around that yacht FINALLY! I imagine that there was some good Dutch being used ...
This is the Pontcysyllte Aqueduct (1805), a navigable aqueduct that carries the Llangollen Canal across the River Dee in the Vale of Llangollen in northeast Wales. Created at the height of Britain's canal building, it was to be a key link between Welsh coal mines, Birmingham manufactories and the seaport of Liverpool. 19 piers with the highest being 124ft and a length of 1,008ft. It is still maintained for public recreation and is an UNESCO World Heritage site.
Britain's canals while initially very profitable were overtaken by the railroads which were far more flexible as to routes and much faster. A reminder of what was high tech in the past is a lot lower now!
