<p>I do not fully agree here. In Germany, I often see a traffic
sign "Vorsicht Düker"</p>
<p>(~ "Attention! Culvert") next to these culverts.</p>
<p>I am not sure why I should pay attention, but it seems that
some</p>
<p>people think that the traffic on the road should notify it.</p>
<p>Maybe because it also often means that there is a <br>
</p>
<p>barrier=fence along the road.<br>
</p>
<p><br>
</p>
<p>In fact I thought that these signs are the explanation for
the <br>
</p>
<p>use of tunnel=culvert on a node.</p>

please be careful:<br>
A "Düker" is not a normal "culvert"!<br>
At a culvert the water is flowing on the same level in the culvert,
normally with airy room above water level in the culvert.<br>
At a "Düker" the water is "pressured" on a level below the normal
water level through the "Düker", so there is no room above water
level.<br>
The normal road traffic has not to obey these sign - but any street
work or use (crawling ;) ) at the waterside.<br>
