Canterbury City Council Development Brief for Land West of Mill Lane, 16th February 2006, says:
Consideration should also be given to improvements at the Blacksole Bridge over the railway to assist pedestrians and cyclists using this route, it is noted, however, that provision of a pedestrian bridge is a requirement of Blacksole Farm development. Improvements to the bus shelter in Canterbury Road and provision of a bus shelter in Margate Road should also be addressed.
It was clear enough then. In fact, it's been obvious to anyone who has looked closely at a map (or walked across Blacksole Bridge) that a busy road with blind bends and no pavements needs sorting out.
