Playing a bit with the Openfietsmap Europe, I discoverd some inconsistencies in one-way streets.
http://www.openstreetmap.org/#map=18/53.93035/-0.78025&layers=C
The Pavement, between Railwaystreet and Grape Lane, is indicated as one-way street, but cycle-route 66 and Way of the Roses are indicated bi-directional.

The unnamed road (Fleshergate?) is indicated as one-way street, but cycle-route 70 and 14 are indicated bi-directional.
Being Dutch I’m lacking local knowlegde to change this.
Maybe someone overthere can modify.
Excuse my mistakes in use of grammar and spelling.
