Tokyo’s Ginza shopping district is set to get an elevated green way. The plan is to turn a 2km urban motorway known as the KK Expressway into the “Tokyo Sky Corridor”. The linear park will then form a green loop around the outskirts of Ginza. The Tokyo metropolitan government published drawings of possible designs for a “pedestrian-centred public space above the KK Line” in February to solicit the public’s views. The project will not be carried out for some time, however. The expressway, which runs above the Nihonbashi river, will be converted from an elevated to an underground road by 2035, so the park development will take place sometime in the 2030s. The KK Expressway was completed in 1966 as part of a plan to relieve traffic congestion in downtown Tokyo.
