Introduction

Tokyo Metropolitan Road Route 116—alternatively known as the Tokyo Expressway, the Tokyo Maruko Yokohama Line, or KK Route (東京高速道路, Tōkyō Kōsoku Dōro) along various segments—serves as a dynamic passage through Tokyo's layered past and ambitious urban future. Traversing key districts such as Nihonbashi, Ginza, and Yaesu, and extending toward Yokohama, Route 116 is both a vital commuter artery and a showcase for Tokyo’s evolving cityscape. Established in the aftermath of World War II on routes once used by Edo-period merchants, Route 116 epitomizes Tokyo’s transformation from a feudal city into a world-class metropolis.

Today, the route is not only essential for economic and social connectivity but is at the heart of major urban redevelopment, including the conversion of elevated highways into green spaces like the Tokyo Sky Corridor. With seamless access from major transit hubs such as Tokyo Station and connections to cultural, commercial, and historical landmarks, Route 116 offers visitors a unique opportunity to experience Tokyo’s blend of tradition, innovation, and sustainability.

Urban Renewal and Sustainability

Expressway Transformation and Green Space Initiatives

Tokyo is undertaking significant projects to relocate portions of its expressways underground, particularly near Nihonbashi, to reduce congestion and restore historic views (E-Housing, 2024). The Tokyo Expressway Company is spearheading the conversion of elevated roadways into the Tokyo Sky Corridor, a pedestrian park inspired by New York's High Line and Paris’s Coulée verte René-Dumont. This elevated green space will offer landscaped walkways, event spaces, and panoramic city views, blending infrastructure with sustainability (Tokyo Metropolitan Government, 2025).

Transportation and Accessibility

Route 116 is integrated with Tokyo’s robust transit network, directly connecting to Tokyo Station and the Yaesu bus terminal. Extensive pedestrian walkways and improved signage ensure a walkable environment from the city center toward Yokohama (E-Housing, 2024). The route is also accessible by multiple Tokyo Metro lines (Ginza, Hibiya, Marunouchi) and JR lines.

Demographic and Economic Impact

Route 116 supports some of Tokyo’s most densely populated and economically productive districts, facilitating daily flows of commuters, shoppers, and tourists. Its redevelopment is anticipated to further boost local economies and enhance the city’s international appeal (Springer, 2018).

Built over Ginza’s former moat, it integrates water features, commercial spaces (Ginza Nine, Ginza Inz), and urban amenities beneath its structure (Tokyo Expressway Company).

Innovations and Resilience

Constructed between 1959 and 1966, the expressway features reinforced concrete and steel designed for seismic safety. Its maintenance is uniquely funded by rental income from the bustling commercial centers underneath.

Transition to the Tokyo Sky Corridor

In April 2025, most of the elevated expressway will close to vehicles and transition into the Tokyo Sky Corridor—a pedestrian greenway prioritizing sustainability and public access, with phased openings from 2025 onward.
