Yes, this separate cycleway into the road means cyclists can travel both ways, since they're bypassing the "no entry" section. However, I'm not sure this road is one-way anyway since there are no arrow road markings visible on imagery. If, for example, it would be legal to drive east from house number 2 to house number 42, this road wouldn't be one-way and instead would need a restriction=no_entry relation at the west end. Do you know if there are any signs aside from the no entry ones indicating that this is one-way (like a blue sign with a white arrow which would be facing westbound traffic)?
