The 4.5 km expressway from Kyobashi to Shibaura first opened in December 1962.
It has been more than 50 years since its opening, and the total length is now about 327.2 km.
Metropolitan Expressway occupies 15% of the routes in the Tokyo metropolitan area (23 wards), supports about 36% of transiting cars, and about 30% of the logistics. It supports transportation in the Tokyo metropolitan area and serves as a lifeline to protect your safety and security.
The Metropolitan Expressway has a total length of about 327.2 km. More than 60% (about 217 km) of the expressway has been open for over 30 years, and 20% has been in operation for more than 50 years.
The Great Hanshin-Awaji Earthquake that struck on January 17, 1995 shocked us all. There is reportedly a 70% possibility that an earthquake directly under the metropolitan area will occur in the next 30 years.
The Metropolitan Expressway is expected to function as a lifeline in the metropolitan area in the event of a large-scale disaster. We are working day and night to protect your safety and security and preserve it for the next 100 years.
Aging and harsh use conditions have caused serious damage to such structures. Therefore, in order to keep the road structures durable for a long time, we are proceeding with a renewal project for the Metropolitan Expressway, while carefully examining structural problems, maintenance problems, and damage conditions.
