Starting work in 2024 means there will be at least a three year gap between the removal of the Spaces for People cycle lanes and the opening of the permanent design. That's three years when families and less confident cyclists will choose not to cycle into town. Three years of lost modal shift and emissions reduction.
I wonder, could the Scottish Government not issue guidance (as it did with COVID-19) allowing local authorities to use TTROs to introduce temporary facilities, on the basis they reduce the danger posed by climate change and local air pollution (and accident reduction for pedestrians and cyclists). After all, the Council and Scottish Government have declared a climate emergency. They have legally binding emissions reductions targets to meet. Doesn't seem outlandish to me.
That would allow temporary versions of these schemes to be created using planters, wands etc, within days. The full TRO could be obtained while the temporary scheme was in place. They wouldn't be perfect and might look a little scrappy, but they would certainly be a step in the right direction.
