How to identify missing/doubled features in ArcMap?

I am working with ArcMap 10.6.1, also have ArcPro 2.2 available.

I have three road layers. All of them have some features in common but at least two have features that the other two do not have. The third one has in exchange an attribute that I would like to keep.

I would like to have all roads combined in one feature class without ending up having one road two or three times in the same place.

I tried to select by location from the first two datasets where roads are in the same place - my idea was to switch then the selection and copy the features to the third dataset. But I don't get all doubled roads selected although I tried different options like "share a line segment with the source layer feature" or "contain the source layer feature" (does contain work with lines?).

Any idea?
