HS2 Ltd<\/a> has delivered the world\u2019s longest box slide to carry a 12,600t bridge into place through a motorway in Warwickshire.<\/p>\n

A team of 450 people from HS2 Ltd.\u2019s construction contractor in the Midlands, Balfour Beatty Vinci (BBV), has slid the Marston Box bridge into position across the M42.<\/p>\n

A specifically designed sliding mechanism drove the box into place on a guiding raft over a distance of 165m \u2013 acknowledged as the world\u2019s longest box slide.<\/p>\n

This method of maneuvering the bridge was used to decrease disruption to road users and is a part of HS2\u2019s plan to relieve the impact of building on local communities.<\/p>\n

The operation was done during the Christmas period, as this was the calmest time on the roads. HS2 and BBV worked in partnership with National Highways to deliver the operation.<\/p>\n

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

The specialist civil and structural engineering company, Freyssinet, has designed this sliding mechanism for maneuvering the bridge.<\/p>\n

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

The bridge will also be employed by HS2 trains headed for Interchange Station in Solihull, Old Oak Common Station and London Euston.<\/p>\n

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

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

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

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
