caption_attribution_description: English: Bohai Strait Tunnel project; the red line indicates the approximate. connection crossing the Bohai Strait.
context_page_description: The Bohai Strait Tunnel or Dalian-Yantai Tunnel is a proposed undersea tunnel construction project across the Bohai Strait to connect Dalian on the Liaodong Peninsula to Yantai on the Shandong Peninsula. The official name for the project is Bohai Strait Cross-Sea Traffic Way.
  Crossing the Bohai Strait, the tunnel would be 123 kilometres long, 90 kilometres of it under water. This would exceed the combined lengths of the two longest undersea tunnels on Earth, the Seikan Tunnel and the Channel tunnel. The tunnel is planned to run more than 100 kilometres under the Strait.
  Operated by China Railway Engineering Corporation, the tunnel would be linked to the Chinese high speed railway system. Cars would be loaded on railway carriages to make the 40-minute crossing. Currently, the Bohai Train Ferry, inaugurated in 2007, crosses the strait in eight hours.
  The project was estimated to cost 200 billion yuan. In August 2014, it was reported that work is likely to commence during the 13th Five-year plan and construction would take ten years to complete.
  As of March 2018, the central government now wants to get construction underway on this bay connection 'as soon as possible'.

The official name for the project is  Bohai Strait Cross-Sea Traffic Way (Chinese: 渤海海峡跨海通道).
  Crossing the Bohai Strait, the tunnel would be 123 kilometres (76 mi) long, 90 kilometres (56 mi) of it under water. This would exceed the combined lengths of the two longest undersea tunnels on Earth, the Seikan Tunnel (23.3 km or 14.5 mi) and the Channel tunnel (37.9 km or 23.5 mi). The tunnel is planned to run more than 100 kilometres (62 mi) under the Strait.
  Operated by China Railway Engineering Corporation, the tunnel would be linked to the Chinese high speed railway system. Cars would be loaded on railway carriages to make the 40-minute crossing. Currently, the Bohai Train Ferry, inaugurated in 2007, crosses the strait in eight hours.
  The project was estimated to cost 200 billion yuan (US$32 billion). In August 2014, it was reported that work is likely to commence during the 13th Five-year plan and construction would take ten years to complete.
  As of March 2018, the central government now wants to get construction underway on this bay connection 'as soon as possible'.
  Plans were formally submitted to the National Development and Reform Commission (NRDC) for approval in May 2019. The project would include bridges from Penglai linking the Changdao islands, then a tunnel under the main Bohai Strait, for a total length of 125 km. If construction was started in 2020, the opening date would be 2039. The estimated budget has risen to 300 billion  yuan (US$43 billion).
