Over 40 hours around Christmas day, a team of 450 workers slid a 13,890-ton section of high-speed railroad bridge about 540 ft over a major highway as part of the U.K.'s multi-billion-dollar London-Birmingham HS2 project.
It marked the end of year when $27 billion of work was in hand, including advances of half of the project’s 10 planned tunnel boring machines (TBMs).
