New Technologies of Expressway Construction to Harmonize with Urban Environments

The Metropolitan Expressway is the urban network to connect the central route and the suburbs, and it maintains transportation in the Greater Tokyo Area. To reduce heavy congestion, especially in central Tokyo, the authors made an effort to connect the “Missing Link” which remained on the Central Circular Route. Finally on 7th March 2015, the authors finished the project of the last section the "Central Circular Shinagawa Route (9.4 km long)”. The covering loop name, “Ohashi Junction” connects the Central Circular Route to the Metropolitan Expressway No.3 Shibuya Route located in densely populated areas. It is not only in response to the surrounding environment including atmosphere and noise, but is also a re-development integrated project and has various methods which are friendly with the environment, such as the creation of the greenery junction. In addition, to connect in the underground two shield tunnels in Ohashi Junction, the authors adapted a non-open enlargement method to reduce the effect on the surrounding environment during construction. In this paper, the authors introduce the methods to preserve the surrounding environment in the “Ohashi Junction” and “the non-open enlargement method” which connects two shield tunnels in the underground by the non-open-cut method to reduce the effect on the surrounding environment during construction.
