The exact detail of cycle route 6 and 68 is ambiguous, there is no dropped pavement to allow a bike to join Meadow Road here https://www.openstreetmap.org/node/1233192746 where the OpenStreetMap route joins it. Could stay on the sidewalk or bounce onto the road or could join the road nearer Holmes Bridge.
Sustrans suggests use of Meadow Road which is natural if cycling towards Exeter Bridge but less so if cycling away from Exeter Bridge and would have to cross to the opposite side of the road.
