Hi
I would suggest that the motorway should not be split until the point
where the two halves physically diverge; instead, where there's a drop
lane, use turn:lanes and destination:lanes tags to indicatethe presence
of the drop lane.
My reasoning for this:
- firstly, there's no physical

The disagreement is that there may be the start of an "exit lane", but
there is no physical separation where the junction has now been modified

Hi Mike,

I think in mapping terms the midlines of each carriageway after the diverge
will look more like a upside-down Y and I tend to do a bit of smoothing to
make it look less abrupt. I think this is what you're getting at (apologies
if not). It's
The technical term is a drop lane. This might later intersect with a
roundabout, join with another motorway or primary road etc. Between junctions,
a single way for each direction is commonplace. At junctions, there are ways
for the through lanes and for traffic exiting and entering the
