屯門至赤鱲角連接路 TMCLKL
屯門至赤鱲角連接路（Tuen Mun–Chek Lap Kok Link），簡稱屯赤連接路、屯赤路，屬於港珠澳大橋香港段相關工程一部分，連接新界屯門區第40區及離島區大嶼山，市民可以更直接地從新界西北前往東涌、港珠澳大橋香港口岸和香港國際機場。
連接路分為南北兩部分，南面連接路稱順朗路（Shun Long Road）。順朗路連接北大嶼山公路往返市區的路段於2018年10月24日與港珠澳大橋同步啟用，通往東涌支路於2018年11月30日開放。
北面連接路稱屯門赤鱲角隧道公路（Tuen Mun Chek Lap Kok Tunnel Road），簡稱屯赤隧道，於2020年12月27日早上8時通車。屯赤隧道通車後，北大嶼山公路和青嶼幹線不再是連接大嶼山和機場的唯一對外道路，亦取消對道路的收費。
屯赤隧道刷新了多項香港紀錄，分別是取代龍山隧道成為香港最長行車隧道、香港首條建設於維多利亞港範圍外並且兩端出入口均位於新界區的海底隧道、香港首條免費的海底隧道、香港首條以鑽挖方式建造（而非以沉管方式建造）的海底隧道、香港首條由法國承建商（香港寶嘉建築）興建的海底隧道，以及香港繼1972年通車的紅磡海底隧道後，相隔48年後再度由非日本承建商興建的海底隧道。同時，工程中使用的鑽頭長達17.6米直徑隧道鑽挖機，是世界最大型的隧道鑽挖機。Wikipedia
Hong Kong Built A $6 Billion Underwater Tunnel
It took more than seven years of design and construction to finish Hong Kong’s epic Tuen Mun-Chek Lap Kok Link (TMCLKL). The project set out to make a massive three-lane underwater highway that could cut travel time to the Hong Kong International Airport by 20 minutes and also reduce traffic on Hong Kong’s other busy highways. Construction had a massive budget of HK $46 billion-- about US $6.1 billion-- but it also broke tons of records, including use of the biggest tunnel boring machine in the world, the Tuen Mun-Chek Lap Kok TBM. This incredible machine is as tall as a 6-story building and reduced the environmental impact as well as the amount of workers-- plus it sped up construction.
There was plenty of other innovation poured into the project, like using the first caterpillar cofferdam in Hong Kong-- a structure used to keep water away from underwater tunnels and provide work space. But there were some setbacks that delayed the project by two years and caused a rift between the Highways Department of Hong Kong and the developers. Thankfully, it finally opened in December 2020. This Northern Connection was Hong Kong’s most ambitious tunnel project yet, elevating it to the likes of other ambitious underwater roadways like Japan’s Seikan Tunnel. Check out our video for everything you need to know about the record-breaking-- and budget-breaking-- Hong Kong construction project, as well as all the innovation that went into the successful connection of the Northern Territories with Lantau Island.
