The Saudi Arabian bridge had to connect to one of the islands, so it would be either Qatar or Bahrain.

Lex Luthor once tried to make Arizona beachfront property. Who know what designs the Legion of Doom may have for the Gulf states? And just don't have as much faith in Ben Affleck as Batman as I did his previous forebears. Sometimes the world feels like it's spinning out of control and I just don't know how many times Superman can spin it around backwards to make everything right again.

Passport control between Bahrain and Saudi Arabia is on this island that separates the spans of the King Fahd Causeway. I've repeatedly tried to find where the border lies - down the middle of this island, or in the sea either side? A big chocolate fish awaits anyone who gets a definitive answer!

Well I suppose the point is you wouldn't be able to walk or drive between the two without the bridge. If the sea level dropped enough, one could walk from India to Sri Lanka, but then again, if the sea level dropped really far enough, you could walk to any country from any country! ......... with one exception, can you work it out?

You couldn't walk from any landlocked country to any other country, or vice versa, unless those countries already had a land border. Although, it would be possible in a few cases where a lake was previously in the way, like Turkmenistan to Azerbaijan.

It seems like it would be something in the Mediterranean, because if we drop the general sea level, the Mediterranean would stop draining once the general level dropped past the land connecting Spain and Morocco. So my guess is Malta and Cyprus.

I've passed through this border more times than I can remember.

The island was constructed artificially. Most maps don't draw international borders in water, but I've seen some maps with the border drawn to the west of the island (placing in the territorial waters of Bahrain), and some maps that bisect the island.

There is nothing of value on the island aside from a few fast food restaurants. With the close ties between the AlSaud and Khalifa families I'm sure it's not a point of contention. There might be something official but with Arab culture being what it is I think it's just as likely that there is an unofficial gentlemen's agreement to share the island.

Whether or not the island is fully within the territory of Bahrain or not, it certainly feels like a legitimate international border, so if nothing else maybe it could be said the Saudis are "leasing" their side.

There are McDonald's on both sides of the island. The one on the Saudi side obeys Saudi laws and closes five times a day for prayer times; there are different sections for men and women and no female employees. The one on the Bahraini side is open all day; seating areas and kitchen staff are all co-ed.

Well that's quite a jump from this quiz to your comment. There aren't a ton of cases where you have situations where two countries that don't border each other are close enough to connect via tunnel or bridge. About the only places without one that I can think of off the top of my head are across Gibraltar, between Eqypt and Saudi across the Red Sea and India and Sri Lanka and I'm not sure if the first two would be viable due to the depth of the water. A cursory look at Wikipedia shows there are at least 28 bridges between the US and Canada and 26 between the US and Mexico.

Sri Lanka and India used to be connected by a natural land bridge. They're in the process of building another causeway connecting Bahrain and Qatar. You could probably connect the Philippines to Malaysia or Indonesia but as both are archipelagos that wouldn't make much sense. Yemen is very close to Djibouti and Eritrea; but there's not a lot of commerce going between these countries. Malta might be possible to connect to Italy but Malta is tiny and I'm sure the cost/benefit analysis wouldn't be favorable. Northern Cyprus to Turkey might be another possibility; but I'm sure the Turks don't want to get further embroiled in the JetPunk argument over whether or not Cyprus is in Asia.

Yes, I have to confess that I hadn't thought the implications of "no physical or river border" through. There are plenty of ongoing cross-border tunnel (and a few bridge) projects in my part of the world, but almost all of these countries have some sort of physical contact already. Maybe a truly new one will be a tunnel between Finland and Estonia? It has been discussed for about a decade. Another one, as you mentioned, is a link between Spain and Morocco. Apart from that... hmmm.... There are some Carribean islands that could be connected (as well as Trinidad with Venezuela) but I assume that there's too few inhabitants and too little cash for something like that.

I took a ferry from Tallinn to Helsinki. Then I drove to Turku to take the ferry from there to Stockholm because it was about 1/10th the price of taking the one from Helsinki.

There are many other bridges and tunnels that connect countries but most of them are excluded because bridges over rivers are excluded, and/or those countries also share a land border.

Wikipedia lists over 60 international bridges. This quiz is very specific and lists the few which provide the sole connection between the given countries. I agree, fun quiz.

Well done, originally the quiz included countries separated by rivers, only traversable by bridges (such as North Korea/Russia, Laos/Myanmar) but they were removed because people get into arguments about what constitutes an artificial border and so on, and it's upsetting when people fall out.

Super easy for me. The only one of these bridges/tunnels I haven't used personally was the Johor Causeway. I've been to Singapore and Malaysia both a few times but never used the bridge.

Also is it impossible to access any country from these two countries? It can't just be that country A is impossible to access from country B , because then you could just go via another country.
