Viaduct construction

Highfurlong Brook Viaduct has become the first on the HS2 project to be completed as work on the project continues to ramp up between London and the West Midlands.

Consisting of seven spans, the viaduct crosses the brook at a height of around 9 metres. Each span is made up of four beams weighing up to 56 tonnes, which were lifted into position over two months to form the backbone of the structure.

Each of the beams – which are up to 25 metres long – were manufactured off site before being delivered over night to reduce disruption for local road users. The deck – which will support the track and electrical systems – will be installed this year, as well as the parapets along either side.
