Скачать или смотреть HS2 completes 4,500 tonne Small Dean viaduct deck slide

In a four-day operation, a massive 4,500-tonne deck was carefully slid across a road and railway line near Wendover, Buckinghamshire. The deck, part of the Small Dean viaduct, stretches 345 meters and is one of 50 major viaducts being built as part of the HS2 project.

Once completed, the new high-speed railway will significantly shorten travel times between the UK’s two largest cities and ease congestion on the southern end of the already-busy West Coast Main Line.

Before the slide began, the viaduct’s concrete and steel deck was assembled in full, with most of the precast concrete slabs already in place. While this added weight to the operation, it will help save time later in the project.

This operation marked the heaviest and longest single-stage viaduct deck slide on the HS2 project to date.
