Here is a few bullet point explaining my reasoning to decide if it is a
tunnel or not :
- I think that most of the exceptions mentioned, are well-known as being
a tunnel (like tunnel in Brussels). Thus it is not a problem for these.
- If you have nothing on top, and it is a passage going
additional things that can be part of the definition:
- passages through embankments are (in general) not tunnels.
- when a road passes over another one, located in a cutting, does not
place the lower one in a tunnel (Antwerp ring road)
- when the road goes under a waterway, the road is in a
AFAIK the tunnel=building_passage, this is not a tunnel, but using the
tunnel tag anyway. I guess the same is true for culvert. I would not
try to come up with a definition that is also applicable to those 2.
Maybe my rule of thumb could be extended somehow for the metrotunnels,
which are clearly
Hi,
First: the interpretations given here to 'tunnel' are much more strict than the
wiki, which leaves much more room for interpretation. A strict interpretation
of tunnel makes the use of tunnel=yes of tunnel=culvert for passages of rivers
underneath a road senseless, just as

Burchtakker (the parallel road) is lowered near the (bicycle) tunnel
under the E34/A11.

I think there is a tunnel under the e34 between Antwerpen en Zelzate.
There used to be a level crossing which was removed and instead they
created an underground passage for it.

@joost schouppe To me that's indeed a bridge,
as you see the same structure as on the motorway bridges : a platform
supported by pillars
A tunnel is generally something that was dig (removing earth/material) and
consolidated from the inside (most often with concrete) like a subway
tunnel if
I doubt one had to dig something for the road to pass under the
railway. There is no "earth" between the road and the sky, only stuff
that humans created, like concrete, stones and asphalt. So a bridge
for me.
I apply the rule: stand on the road, look up, which layers of material
do you "see"

Hi,
1. This is a bridge: no doubt.

Hello,
I would consider each situation from #3 to #9 here as a bridge.
Here’s why. If there had never been a railway, the road would be where it is
now, and it is perfectly flat and aligned with the houses nearby (implicitely
level=0 and layer=0 in OSM).
On the contrary, the embankment is an
I think some passages are called a mole pipe, but that makes it not a
tunnel.
Don't have tunnel vision: All your examples are railroad bridges.
A tunnel has mosttimes also a depth: it lies not under, but beneath
something and/or crosses several things.
Also, sometimes a traffic sign F8 can

Het kan zijn dat ik iets mis - het is een zware dag geweest op het werk
