Align hits key milestone on HS2 Colne Valley viaduct

HS2’s main works contractor Align JV has completed the first set of V-shaped bridge piers for what will be UK’s longest railway bridge
The  V-piers are designed to support the viaduct deck over a series of lakes the Colne Valley Viaduct crosses between the end of the London tunnels and the start of the Chiltern tunnels.
Designed to bear the weight of the 80m wide arches over the lakes, the ‘v-piers’ are twice as large as simpler piers that carry the viaduct over land
