Shatin to Central Link (SCL) is a major infrastructure investment currently under construction in Hong Kong and aims in connecting a number of existing railway lines passing through different districts of the island. The line passes through already developed urban areas, encountering different topography and geology conditions, which require not only the application of different construction methods, but the use of different types of the same equipment as explained by two of the leading companies in the tunneling construction industry, having undertaken the construction of specific tunnel sections.
This week marks a milestone in the Elizabeth River Tunnel project in Virginia. The project is one of the largest infrastructure projects occurring in the U.S. right now. It will place a two lane tunnel next to an existing tunnel connecting Norfolk and Portsmouth, Virginia and thus double the tunnels capacity and reduce commute times. SKW Contractors team, a joint venture between Skanska, Kiewit, and Weeks Marine, are overseeing the public-private partnership project and are responsible for submersing eleven 16,000-ton hollow concrete elements into a special trench at the bottom of the Elizabeth River.
A second harbour tunnel is within the State Infrastructure Strategy's development plans in Sydney. The new tunnel will be an extension to the M2 motorway, connecting Balmain to Lane Cove, and will offer motorists a bypass to the congested inner city.
Passengers flying out of Toronto’s Billy Bishop Airport have been accustomed to a unique additional step to reaching their gate when trying to catch a flight. Instead of being dropped off in front of the airport and walking inside to receive one’s boarding pass and go through security, travelers flying through Billy Bishop Airport must take a 90-second ferry ride across Lake Ontario to reach their gate. Billy Bishop Airport is located on an island in Lake Ontario, located two miles from the downtown area. While many passengers enjoy the ferry ride, others have complained that the quarter-hourly crossings cause a lot of stress for passengers trying to make their flight.
Slated at $10 billion, construction on the Fehmarn Belt Fixed Link could start as early as this year. At 11 miles long, the completed project will be the longest immersed tunnel in the world. It will run beneath the Baltic Sea and connect Denmark to Germany between the islands of Lolland and Fehmarn. Long in the planning, the bill finally giving the project the green light passed its first reading in the Danish Parliament this month. Construction could be completed as early as 2024.
The underwater tunnel is a huge project with a cost at around 36 billion US dollars, with a length twice as long as the Channel Tunnel is and it will be built in the most dangerous earthquake zones in Asia. When the tunnel is completed, the Dalian tunnel will be the longest undersea tunnel in the world.
A £1.4 billion plan proposes replacing much of the A303 route that runs past Stonehenge with a new route that includes a 2.9km (1.8 miles), deep-bored tunnel, just a few hundred meters south of the monument.
