Yes, I feel the same. And I agree that most of the Paul Dudley White Path should not be retagged. 

DCR designates the 3-foot sidewalk between BU Bridge and DeWolfe as part of the Paul Dudley White "shared-use path", which would mean tagging for as cycle=designated and foot=designated, like other sections of PDW.

But the one-way cycle track drawn here is not consistent with mapping conventions. OSM Wiki says that in-road cycle lanes separated by paint only should not be drawn as separate ways, but added as tags to the highway feature.

I don't know of a better way to route westbound cyclists on this section. Since fixing the map can't fix the infrastructure, I think it's best to keep it consistent with the DCR designation and OSM convention. 

Your thoughts?
