Cycle lane continuation required

Shared cycle lane around the roundabout seems to vanish when approaching A4144/woodstock road from Sunderland Avenue exit, unsafe to join carriageway without first cycling on pavement which is not currently marked as a shared cycle/pedestrian pavement until after blandford avenue. Alternative cycle route on other side of road is not suitable as it's not wide enough for bikes in both directions (especially with childrens trailers!) and requires unnecessary crossing of 2x busy sets of lights at roundabout to then cross back over further down the road. Please add shared pavement markings from roundabout to blandford avenue where they currently restart anyway.
