Construction of HS2’s Colne Valley viaduct segments has started

Work on the UK’s longest railway bridge ramped up earlier this week as HS2 began production of the first of 1,000 huge concrete segments that will eventually be used to form the deck of the Colne Valley railway viaduct. Stretching for 2.1 miles across a series of lakes and waterways just inside the M25, the bridge will be made up a number of shallow spans up to 80 metres long that leap across the lakes.
