When road or building work requires space to be removed from the carriageway, who gives up the space? In Britain, roadworks often occupy cycle facilities, with no provision of alternatives.
In other countries cyclists often get a better deal.
This photo, from the centre of Copenhagen, shows that when building work requires space to be taken away from the pavement and cycle track, a temporary facility is constructed on the road.
Admittedly, the provision is narrow and well below the width of the cycle facility that had been replaced, but cyclists at least have been considered.
