I saw some (in a Youtube vid) so narrow, in whatever mountain, that people doing MTB rides had to... unscrew the handlebar to make it loose enough so that the handlebards could then be turned 90 degrees. Otherwise the bike simply wouldn't fit (and there was no other way than that tunnel).<p>I forgot where that was.<p>EDIT: found it, it's in Switzerland. These people are insane: <a href="https://youtu.be/vZgiWYY9euM" rel="nofollow noreferrer">https://youtu.be/vZgiWYY9euM</a> (just look at the intro and you'll see both why they're completely insane and the narrow tunnel)
There are mixed pedestrian/vehicle underpasses for the Yamanote train tracks in Tokyo as well, though a bit taller (1.5m).<p>My understanding is that when the tracks were originally put in they were near the edge of the bay so there were still boats. However, as Tokyo expanded and the land filled in the boat tunnels were filled as well and became pedestrian and vehicle underpasses.<p><a href="https://thetokyofiles.com/2013/06/30/sengakuji_underpass/" rel="nofollow noreferrer">https://thetokyofiles.com/2013/06/30/sengakuji_underpass/</a>
Somewhat OT, but why is it that (I'm assuming native from the accent) English narrators in Japanese produced shows seem to always have a certain recognizable ebullient tone to their narration?<p>[edit]<p>It's not just the effusiveness, but also there seems to be a high-rising terminal.
This reminds me of a tunnel outside of the Interlaken Ost train station in Switzerland. It was roughly 5 ft tall and there were many people using it as a shortcut to the train station.<p>If you pan through here on a Google Maps streetview you can see people making their way to the railway station:

In London the closest we've got is probably Coppermill Bridge:<p><a href="https://www.youtube.com/watch?v=LlSd0LW0XdU">https://www.youtube.com/watch?v=LlSd0LW0XdU</a><p>Most people duck while cycling through, but i find it better to slide forward off the saddle and hang off to one side, because you can keep looking forward more easily.
Impressively low. When I was a student (in Tübingen, Germany), I regularly had to use a similar tunnel under an old freight train depot, but this one had a luxurious height of 1.9 meters: <a href="https://www.tuepedia.de/images/b/be/Eisenbahntunnel.jpg" rel="nofollow noreferrer">https://www.tuepedia.de/images/b/be/Eisenbahntunnel.jpg</a><p>It was regularly flooded, however.
Watching that brought back a few memories. I walked (well, quickly scuttled) through that tunnel the last time I was in Japan. For me, a mild claustrophobe, it was a somewhat scary but at the same time somewhat exhilarating experience.
