connect to the ends of roads so routing still works
RP: is there a way to create amenity=ferry_terminal at each end node?
HB: just one survived the dupe test, and it was a tiny little one which probably has nothing in the way of terminals to worry about. uploaded for the mainland 19 jan 2011 in changeset 7009751.
SD: you can add amenity=ferry_terminal at each end node by selecting 'First and last nodes' as the option for 'Apply To' for the tag.
