Two shield tunneling machines for Metro Line 14 succeeded in going through Metro 7 and 10 tunnels at the same time recently.
The construction team carried out strict monitoring to ensure the safety and timely adjustment of the tunneling machines.
Metro Line 14, running through Jiading District, Putuo District, Jing’an District, Huangpu District and the Pudong New Area, will relieve congestion on Metro Line 2 and greatly support regional development.
Over the past two years, altogether 41 metro line construction projects have succeeded in going through lines in operation.
