HS2 and BBV worked in partnership with National Highways to deliver the operation.<\/p>\n<p style=\"text-align: justify;\">The 86m-long structure with a base, three walls and a top slab were constructed on land next to the motorway during the last six months. It was designed by a JV containing Mott MacDonald and Systra, working as the representative of BBV.<\/p>\n<p style=\"text-align: justify;\">The specialist civil and structural engineering company, Freyssinet, has designed this sliding mechanism for maneuvering the bridge.<\/p>\n<p style=\"text-align: justify;\">Once operational, the entire structure will be about 190m long and carry HS2 trains through the motorway towards Crewe in the north or Birmingham Curzon Street in the south.<\/p>\n<p style=\"text-align: justify;\">The bridge will also be employed by HS2 trains headed for Interchange Station in Solihull, Old Oak Common Station and London Euston.<\/p>\n<p style=\"text-align: justify;\">Mike Lyons, HS2 Ltd.\u2019s civils delivery director, claimed: \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.\u201d<\/p>\n<p style=\"text-align: justify;\">In addition, Sasan Ghavami, Balfour Beatty Vinci\u2019s construction director for the project pointed out: \u201cWe\u2019re extremely proud to have successfully delivered the world\u2019s longest box slide. It\u2019s a huge achievement for our project team and everyone connected with Balfour Beatty Vinci.\u201d<\/p>\n<p style=\"text-align: justify;\">The bridge was driven into place at a speed of 4m per hour and took 40 hours during a 10-day closure of the motorway between Junctions 9 and 10. The motorway opened to traffic again on 3 January.<\/p>\n<p style=\"text-align: justify;\">BBV finished preparation work to install the Marston Box bridge, containing making a 3m deep cutting, installing and linking new drainage, and making foundations in February last year.<\/p>\n<p>[embedyt] https:\/\/www.youtube.com\/watch?v=DxGd83rzcts[\/embedyt]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>HS2 Ltd has delivered the world\u2019s longest box slide to carry a 12,600t bridge into place through a motorway in Warwickshire.
