A monumental achievement involving over 1,600 Arup staff, much of Arup's work on High Speed 1 is hidden from view. Building the link involved tunnelling beneath 2,600 properties and under 67 bridges, 12km of surface railway, 600 pipelines and four London Underground stations.

Elsewhere, High Speed 1 is on show to the world. It brought about the rejuvenation of the Grade I listed St Pancras station and it crosses the River Medway on the longest-span, high-speed rail viaduct in Europe.

In places, Arup also contributed to the environmental aspects of the project. Soil from construction was used to help the link to sit unobtrusively low in the landscape. The project also created 250 ha of new native woodland around the line.

Completed on time and within budget, High Speed 1 has transformed travel between the UK and the rest of Europe. The link has also helped to bring in over -10 bn of regeneration investment to create new quarters for London in Stratford and King's Cross/St Pancras and a new city in Ebbsfleet, north Kent.

A crucial part of London's bid to host the 2012 Olympics, High Speed 1 has helped to create the opportunity for significant long-term benefits for the capital and the country.
