OpenStreetMap is topology aware. This means that if two ways cross each
other and the place where they intersect is a routing node, then there
WILL be an OSM node there. If they intersect without an OSM node, then
the intersection is NOT a routing node (e.g. a bridge or tunnel).
In these cases you can calculate the position where the ways intersect
but this is not of any use for routing.
