Giant Launch Girder Begins Deck Construction on UK's Longest Train Viaduct
Abstract
A 770-ton sliding girder will place around 1,000 concrete elements along the 2.1-mile-long Colne Valley Viaduct on the emerging London-Birmingham high speed railroad, known as HS2. The Align joint venture is building the viaduct across a series of lakes and waterways northwest of London under a $2-billion design-build contract. Already 90 per cent of the program's enabling works are done. HS2 has a $56-billion total budget. The HS2 project has just completed the first full year with $6.8.8 billion of work.
