Hi,

Our team at Mapbox has been adding turn lanes in several cities in the
US. In some cases, bi-directional roads need to be converted to
dual-carriageways when there is a physical separation.  However, we
are finding it difficult to create dual-carriageways since most major
roads already have route relations and there is a danger of breaking
route relations.

We are documenting the process here:
https://github.com/mapbox/mapping/issues/180#issuecomment-279367407
Would love the community's inputs on how we can avoid relation breakage.
