Construction of a 37-mile section from London north will be pushed back two years amid inflationary pressure and increased project costs.

The joint venture working on the London-Birmingham high-speed rail project says this is the world's longest slide of its type.

Contractors have launched five of the 10 tunnel boring machines set to dig 64 miles of tunnels for the $46.5-billion project.

A 525-ft-long sliding girder, originally built for a Hong Kong project, will place around 1,000 concrete elements of a 2.1-mile viaduct for a new high-speed railroad. 

As the first anniversary of work on the U.K.’s 225-km London-Birmingham high-speed railroad (HS2) is reached, news of a major bentonite leak of more than 1,500 cu m at the project’s first tunnel has revived opposition to the project.

$17-billion, 230-km HS2 project will extend service from London to Birmingham England.

Robotic arms for tunnel-boring machines, concrete reinforcement made of old wind turbine blades and machine learning to reduce concrete waste are among innovations emerging from the $16.7-billion civil construction program for the U.K.’s London to Birmingham high-speed railroad. Construction began late last year.

A team of New Zealand-based software designers that brought digital 3D modeling to engineering geotechnics less than two years ago recently launched an upgrade to their software. It is now being used on some major projects, including the U.K.’s multibillion-dollar London-Birmingham high speed railroad (HS2).
