High Speed (HS1)

High Speed 1 (HS1) is the railway between St Pancras in London and the Channel Tunnel, which connects with the international high speed routes between London and Paris, and London and Brussels.

Skanska completed the biggest and possibly one of the most complex sections of the HS1 route, which ran for 15.2km from Willesborough in Kent at the eastern end, to Charing Heath at the western end.

It included laying 17km of track, with cut and cover tunnels through the centre of Ashford, with links to the existing international station.  The Skanska programme kept the trains running on the existing rail network, while installing the completely new railway through the centre of Ashford.

The carriage berthing sidings on each side of the station were re-located to enable the viaduct construction to start in 2000.  This required major lengths of cut and cover box tunnels, diaphragm walls, bored piling and roof slabs.
