Organizing officials have nearly mapped out an “Olympic lane” from Narita Airport to the Tokyo waterfront that can be used only by Games-related vehicles during the 2020 Tokyo Olympics and Paralympics.

The Tokyo Organizing Committee and the central and Tokyo metropolitan governments are targeting about 60 kilometers of the Metropolitan Expressway Bayshore Route, the Harumi Route and the Higashi-Kanto Expressway for the restricted lane, sources said.

They are also considering an Olympic lane between the Tokyo waterfront and Haneda Airport. But doing so would have a huge impact on regular traffic, so extending the lane between the Tokyo Port Tunnel and Haneda Airport is highly unlikely, the sources said.

Olympic lanes have been used in previous Games. Their purpose is to ensure smooth transport of Olympic officials and athletes.

Tokyo officials have yet to decide on when the Olympic lanes will be closed to ordinary traffic and whether to fine motorists who use the restricted routes. The transport management plan will be submitted to the International Olympic Committee and hopefully approved by the end of this year, the sources said.

The Games-related vehicles are expected to include 2,000 buses mainly for athletes and 4,000 passenger vehicles for IOC executives and other officials.

Olympic lanes will not be used on the other mainly two-lane sections of the Metropolitan Expressway because travel time would not likely be reduced.

But restricted routes are planned for multiple-lane local roads around the Olympic Village and the sporting venues.

Under earlier plans, Tokyo was to provide Olympic lanes with a total length of 317 km. But that distance has been drastically reduced.

To ease traffic congestion during the daytime during the Olympics, officials are considering a “road pricing” system with changing tolls on the Metropolitan Expressway, such as adding about 1,000 yen ($9.20) to the fare for private vehicles during the day and halving the price for all vehicles in the late evening.

They are also considering limiting the number of cars that can use certain roads and promoting car-pooling.
