While many people may have heard of DJ Casper’s ‘Cha Cha Slide’, we doubt so many would have heard of HS2’s ‘Viaduct Slide’.

While sharing a similar-sounding name, the Viaduct Slide is not, in fact, a catchy dance move, but rather a multi-organisational and multi-million-pound, first-of-its-kind operation.

The slide sees a metal deck weighing more than 3,000 tonnes slide inch by inch over the M42 and M6 motorway, Near Coleshill, Birmingham, creating a platform for the future HS2 trains to travel over on their journeys to the North and South of England, all with the help of ‘frying-pan technology’.

This isn’t the first time that the slide has taken place, with the first phase of the project in June seeing the HS2 ‘east deck’ slide 119m over the M6 at the Junction 4 slip road, just adjacent to the motorway.

So, in anticipation of the mammoth-sized operation, we visited the works to find out how the ‘Viaduct Slide’ works.
