please be careful:
A "Düker" is not a normal "culvert"!
At a culvert the water is flowing on the same level in the culvert, 
normally with airy room above water level in the culvert.
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.
The normal road traffic has not to obey these sign - but any street work 
or use (crawling ;) ) at the waterside.
