1 Overview of the Revitalization of the Tokyo Expressway ( K K Expressway)••••

The elevated roads currently surrounding the Ginza KK expressway, , with its overall length of 2km, will be revitalized into the "TokyoSky Corridor."Due to the development of new Central Circular Route of Metropolitan Expressway (New Kyobashi Connecting Road), use of theexpressway by motor vehicles has greatly reduced.
This project will transform the expressway, formerly for the exclusive use of motor vehicles, into a public space for pedestrians.
Making full use of plant and art installations, as well s viewpoints for gazing out at cultural centers in the region such as Yurakucho,
Shiｍbashi and Ginza, the revitalized expressway will be a base for sightseeing, attracting attention around the world.

KK Expressway Revitalization Project: Goals～Revitalizing the overhead space of the KK Expressway for use as a public space for pedestrians, we will enhance Tokyo's appeal and generate value ～Creation of an open network for pedestrians through a transition from a “vehicle-centered” to a "human-centered” approach

Creation of green infrastructure as a symbol of an advanced city where“humans and greenery coexist in mutual prosperity”
Creation of an open place for relaxation in order to enhance “regional value and appeal”

Future Visions
Future Vision １

Construction of a broad pedestrian-friendly network that makes best use of the form of the elevated road

Future Vision 2

Construction of a large-scale green network that makes use of connecting outdoor spaces

Future Vision 3

Enhance regional value and appeal by making use of existing features

34 Contents of Development, the Overhead Space（Tokyo Sky Corridor）
Pedestrian spaces, plaza spaces
In addition to space for pedestrian traffic, the sections of the road with a width of approximately 16m or more will help to form a well-balanced space; we will use
the different widths for the development of open-space plazas for activities and viewpoints where people can stop and enjoy views of the city near the intersection
with Harumi-street and other major roads.

4 Contents of Development, the Overhead Space（Tokyo Sky Corridor）••

We will organize planting and various service functions when appropriate, as well as consider theintroduction of art to create a comfortable space that all can enjoy.
With regard to next-generation mobility, we will consider the functions to support pedestrian
movement in the overhead space of the KK Expressway as well as functions, such as sightseeing, sopeople can enjoy moving across the space. Meanwhile we will continue to factor in the needs of thelocal community.

7 Operation Management（Scheme, Utilization etc. ）•Upon revitalization, the present facility owner, Tokyo Kousoku Expressway Co.,Ltd will, in principle, perform
operation management through the succession of the present operation management scheme which derives

According to the KK Expressway urban plans, in December 2023 the expressways designation changed from that of a road to amajor public facility in the Yurakucho/Ginza/Shinbashi District Plan, which defines redevelopment promotion districts.

•The construction will begin in the mid-2020s, with a target completion date for all sections in the 2030s to 2040s. In
cooperation with the surrounding community development, we will work to open up some sections early through phased
construction in order to quickly create the value and appeal of the urban space.
