CADO
In the Netherlands we have the phenomenon CADO, which stands for Calamiteiten doorsteek .
Pass throughs that can be opened to emergency services.
As a general rule: we don't map CADO's.
Some CADO's are mapped. These are mostly lanes that can be opened for the public in case of an accident blocking the regular road. An example on the N59, Ooltgensplaat.
