HS2 moves first huge Delta Junction viaduct section over M42/M6 link road

HS2 has moved the firstviaduct section into place over the motorway network in North Warwickshire, which it says marks a milestone for the project’s Delta Junction as HS2 reaches peak construction in the region.

Contractors working for HS2 have used a specialist push-pull technique to move the 84 metre, 300 tonne steel viaduct section into place over the westbound link road between the M6 and M42 near Coleshill.

This is the first of two moves to install the deck for HS2’s ‘East Link Viaduct’, which is part of the triangular Delta Junction. The second operation in April will create the full 158 metre long composite deck over both westbound and eastbound motorway link roads. Further work, including in-situ concrete deck works and parapets installation will be undertaken to complete the structure.

It was delivered by specialist steelwork company Victor Buyck Steel Construction (VBSC), working on behalf of HS2’s main works contractor Balfour Beatty VINCI (BBV). Using a push-pull jacking system which gives greater flexibility during the launch operation, it was the first time VBSC have used their specially designed technique in the UK.

The team completed the move ahead of schedule in a total of 11.5 hours during a weekend closure of the motorway link roads. Working in close collaboration with National Highways, the roads were re-opened at 2.35am on Sunday.

Before the end of this year, a similar two-stage operation will move the identical ‘West Link Viaduct’ which runs parallel to the East Link Viaduct.

This section of the triangular Delta Junction enables high speed trains to travel between London, Interchange Station in Solihull and Birmingham Curzon Street Station.
