Being one of the most intensive streets of Istanbul, Halaskargazi Street can not offer a controlled transportation to the pedestrians and cyclists. As a solution to this problem a second layer rising above the columns have been proposed. The platforms which are connected vertically by means of ramps and elevators at the bus stops and similar points, at the same time, aims to increase the green areas which have dramatically reduced. Such intervention to be made at city scale has also been considered as radially sustainable.
