A site team of 450 slid a 12,600 tonne bridge a record 165 metres to position it across the M42 during the Christmas period.<\/p>\n

The team worked around the clock to move HS2\u2019s Marston Box bridge into place in an operation which took 40 hours, at a speed of 4 metres per hour.<\/p>\n

HS2 Ltd\u2019s Civils Delivery Director, Mike Lyons said: \u201cThis is the first box slide of its kind over a motorway in the UK, and we believe it\u2019s also the world\u2019s longest slide, so it\u2019s a great achievement for HS2 as we quickly approach peak construction.<\/p>\n

Over the last six months, the 86 metre-long structure was built on land next to the motorway.<\/p>\n

The structure, developed by a Design Joint Venture of Mott MacDonald and Systra, working on behalf of BBV, has a base, three walls and top slab.<\/p>\n

The sliding mechanism, designed by specialist civil and structural engineering company Freyssinet, allowed the box to be pushed into place over the motorway on a guiding raft over a distance of 163 metres \u2013 which is believed to be the world\u2019s longest box slide.<\/p>\n

On completion, the whole structure will be around 190 metres in length, and will carry HS2 over the motorway as it heads north to Crewe, or on its southward journey as it loops into Birmingham Curzon Street or continues straight on to Interchange Station in Solihull, Old Oak Common Station and London Euston.<\/p>\n
