Construction of the K7 launch shaft and associated TBM assembly facilities has been progressing ahead of the start of excavation next year.<\/p>\n

The tunnel forms part of Poland\u2019s developing high-speed rail network under the Port Polska programme and will provide a new underground rail connection through \u0141\u00f3d\u017a for services using the planned high-speed network.<\/p>\n","protected":false},"excerpt":{"rendered":"
