Re: [OSM-talk-be] bridge or tunnel?

Well...

My feeling is there is no tunnel there. Even when the under-passage is quite 
long in regard with the width.

Could the railway bridge (at the 2nd link) be considered a viaduct ?

Hmm, how about this case:

https://play.osm.be/historischekaart.html#18/50.84125/4.03590/dhm_hill-osmroads
https://www.mapillary.com/app/?lat=50.8409878896054=4.035847194701205=17=CemcYfldMKwaCCdn0eK2bQ=photo=0.5005982815044207=0.34925403860156434=0

It's a road that was dug under a slightly raised train track, but it looks like 
a bridge. Or is it bridge for the road, tunnel under the train, bridge again :) 
?

Hi Stijn and all

In my opinion, a tunnel is something that was dug, in a hill or in mountain, 
under a river, ...

Otherwise I would think of a viaduct.

In that regard only your case #2 is a tunnel.

Just my 2 cents...

Hi,

1. This is a bridge: no doubt.
https://www.google.be/maps/@50.9628551,5.0810297,3a,75y,328.21h,89.12t/data=!3m6!1e1!3m4!1sXz43z9vWyUiOpCVTschIUQ!2e0!7i13312!8i6656?hl=nl

2. This is a tunnel: sure enough.
https://www.google.be/maps/@50.6138142,5.5973887,3a,75y,97.64h,84.03t/data=!3m6!1e1!3m4!1sRvKwojNbhvMdSBWG3zViLw!2e0!7i13312!8i6656?hl=nl

3. This looks like a tunnel, no? Or is the fact that the railway is on an 
embankment enough reason to make it a bridge?
https://www.google.be/maps/@50.5508531,4.7216376,3a,89.9y,51.8h,87.45t/data=!3m6!1e1!3m4!1s4GoklQWnN5bW6ugdo1grmg!2e0!7i13312!8i6656?hl=nl

4. This one looks more like a bridge:
https://www.google.be/maps/@50.5923923,4.6668939,3a,75y,57.67h,80.29t/data=!3m6!1e1!3m4!1s4y-C9gvI9ZsUk9jcNQX4eA!2e0!7i13312!8i6656?hl=nl

5. And this? Brunnel or tidge?
https://www.google.be/maps/@50.5214486,4.8868137,3a,75y,27.85h,81t/data=!3m6!1e1!3m4!1sx0n9EuFTEx27S4sCQ--GPg!2e0!7i13312!8i6656?hl=nl

6. And if it gets shorter?
https://www.google.be/maps/@50.5317414,4.9485687,3a,75y,39.18h,91.35t/data=!3m6!1e1!3m4!1sdTd6puiPIvGKsLBzeCzB6Q!2e0!7i13312!8i6656?hl=nl

7. And this?
https://www.google.be/maps/@50.8660892,4.3648486,3a,75y,333.02h,85.73t/data=!3m6!1e1!3m4!1swvUHgLYhl8R5IXGVJ2QWiQ!2e0!7i13312!8i6656?hl=nl

8. A bit more complicated: not only a railway, but also the platforms on a 
bridge? Or above a tunnel?
https://www.google.be/maps/@50.8101922,4.3991964,3a,75y,63.96h,87.57t/data=!3m6!1e1!3m4!1s2ioHz72P7Ju0aTcMLalGKg!2e0!7i13312!8i6656?hl=nl

9. And if you turn around:
https://www.google.be/maps/@50.8101922,4.3991964,3a,75y,258.54h,101.02t/data=!3m6!1e1!3m4!1s2ioHz72P7Ju0aTcMLalGKg!2e0!7i13312!8i6656?hl=nl

I am curious about your opinion...
But of course, what those things are, is not really the question. How should 
they be mapped? That's the question.

Regards,

StijnRR
