The meme is maybe a bit silly, but I thought it was neat - getting attention on Imgur. hehe

In Scotland, they have a "Ferris wheel" for boats, which also includes a more extreme bridge.

And Norway is seriously considering building a tunnel for ships. (We're building so many tunnels these days that one might wonder if there is some conspiracy to turn us into an underground civilization.)

There are even more ship bridges in the Netherland. And also a ship bridge over a river in Germany. (Ok, hard to see, but there is a channel up there:

and the old one

and more here: http://www.gehe-trading.de/Mittellandkanal%202005%20100%20Jahre%2001.htm

There are plenty of tunnel in France ("Rove tunnel" with more than 7200 m long!)
or mroe than 5km https://en.wikipedia.org/wiki/Riqueval_Tunnel
but also in Germany:

When will we get our boat "rail" crossings?  :)



This is the Big Chute Marine Railways in Ontario, Canada.

The French tunnel has an impressive length, more so considering when it was built, but it doesn't look suited for big ships. More like barges and small boats. Not something for big ferries / small cruise ships.

Well the Rove tunnel (https://de.wikipedia.org/wiki/Tunnel_du_Rove) was built 4m depth (15,4 m height) and 1500 metric tons displacement. It caved in though. That is already not too small, and close to the norwegian tunnel. It also was connected to a sea, the mediterran in this case.

Strange that they thought it worth it to build that tunnel. By the time it was built, both trains and trucks should have been viable alternatives if the sea is too rough for river boats.

It makes perfect sense. If the road is to pass under the water, the road has to go down about 12 metres. If it is to pass over the water, the road has to go up about 16 metres, or about 35 metres if the water is meant for sailing yachts. So having the road pass under the water is the most sensible thing to do. Shorter ramps, less earth to move and easier for cyclists, who only have to go down 9 metres (the cycling path is higher than the main road).

In case of the Rove tunnel: 1500 tons per ship is a lot of trucks (about 100 or so!) Not sure in 1916 that was such a good alternative. But in 1963 it was good enouhg, otherwise the would have rebuilt the tunnel.

The English article I had switched to only had the year it opened, so I didn't know how long ago the construction had started. Another important aspect is the cargo's origin and destination. If the goods come by ship and leave by ship, or are made or consumed right by the port, having to put a train in between will cause delays and require more manpower. Otherwise, the land vehicles are needed anyway.

Also the main port area of Marseille has moved. The old port close to the city is now mostly for ro-ro ships (including ferries and pure car carriers), a little bit of containers, grain and the marina of course. Not something that attracts a lot of inland shipping. The main port, with coal, ore, petroleum and large scale containers, has moved to Port-Saint-Louis-du-Rhône and Port-de-Bouc. All just from viewing the area in Google Earth, so I'm not 100% sure. But with the main port area directly at the mouth of the Rhône, the river boats no longer have to pass that mountain.
