One-way streets incorrectly tagged with bike lanes on both sides

Posted by ellieayla_ on 29 May 2025 in English.

In the Halton region in Ontario Canada (and probably elsewhere), many two-way streets split with a boulevard are modelled as two one-way street segments (eg way/286996210).

It has been observed (2025-May) that many (2025 May, n=244) of these are tagged https://wiki.openstreetmap.org/wiki/Tag:cycleway=lane, which incorrectly renders in cycling maps as having a bike lane on both sides of the street.

Eg https://www.cyclosm.org/#map=18/43.33590/-79.81317/cyclosm

Many (all?) of these should be tagged https://wiki.openstreetmap.org/wiki/Tag:cycleway:right=lane instead

OSRM appears to disagree with how https://www.cyclosm.org/#map=18/43.33567/-79.81291/cyclosm is coloured, according to https://github.com/Project-OSRM/osrm-backend/issues/4943

What’s the proper assumption for what https://wiki.openstreetmap.org/wiki/Tag:oneway=yes + https://wiki.openstreetmap.org/wiki/Tag:cycleway=lane means?
