HS2<\/a> viaducts form a small part of the Delta junction, which is a large triangular intersection being built for HS2 near Birmingham.<\/p>\nThe Delta junction will allow high-speed trains to travel over motorways and roads, rivers, and floodplains, connecting services to Birmingham and the mainline.<\/p>\n
The junction will have over two miles of track<\/h3>\n
Due to the nature of the high-speed trains, which will travel up to 360km\/h (223mph), the junction needs to be stretched out much further than a motorway junction. Therefore, including underpasses, flyovers, and viaducts, the track will stretch to 2.6 miles.<\/p>\n
The two HS2 viaducts completed over Christmas, the Water Orton viaducts, are at the northernmost end of the junction and will allow southbound trains to join the spur into Birmingham.<\/p>\n
The viaducts were completed by Balfour Beatty VINCI engineers over a five-day closure throughout Christmas, and now work can move to the viaducts over the A446 and M42.<\/p>\n
