From Cameron Rose's blog:

"February is the planned date for work to change the layout of the Argyle Place/Melville Drive junction."
Cameron says he doesn't have the "new plans to hand" (don't know if that means that he does have access to them) but he does specifically mention that the plans include:
"widening of the off road pedestrian cycle path to the west of Argyle Place to Meadow Place"
Does anyone have details of what is planned here?
