There have been increasing cases where environmentally friendly tunnel structures are being adopted to the Metropolitan Expressway Network construction. The road tunnel structure needs road tunnel ventilation system for incoming traffic safety and comfort. However , there has been a concern about an environmental impact on the buildings adjacent to the ventilation station since the road tunnel ventilation system expels road tunnel air intensively at its ventilation station outlets.
 In this project, the new NO2 removal system for the road tunnel was introduced into narrow ventilation station of Tokyo Metropolitan Expressway.
