Hello LockOnGuy;
I removed these tags because they didn't conform to the rule In OpenStreetMap about adding the embankment and layer tags,
When we add embankment tags it distinguish the ways are placed on a raised bank Unlike bridges,
a layer tag is rarely needed for embankments and should not be used without a good reason.
and these ways does not intersect with other ways to add layer tags,
Please see wiki OpenStreetMap
