This is in response to a high number of collisions having been recorded at this location involving vehicles turning right from Lumley Road, and northbound traffic on St Dunstan's Hill. Local residents and stakeholders have also raised concerns about this junction. We are now holding a public consultation on our proposals, running from 7 June to 18 July 2021, and you can find details of how to take part below.

We propose making the exit from Lumley Road onto St Dunstan's Hill left turn only. To enforce this, we propose installing a pedestrian island in the carriageway at the end of Lumley Road, which would help prevent vehicles from turning right. This island would include dropped kerbs and tactile paving. As well as prohibiting the right turn, this would also provide a safer and easier crossing point for pedestrians and cyclists crossing Lumley Road.

From impact assessment

• . In the past three years, there have been eight collisions at this junction. Of these collisions, four have involved motorcyclists (vulnerable road users).
• The proposed (triangular type) pedestrian island will make it easier for disabled pedestrians to cross Lumley Road safely. The island will have sufficient space for a wheelchair user. Tactile paving will be installed to help a visually impaired pedestrian identify the edge of the footway and the cycle track.
