Concrete poured at night for Birmingham HS2 viaduct

Images have been released showing building progress on the viaduct to bring high-speed trains into Birmingham's Curzon Street station.

Concrete has been poured to create the first two 90m (295ft) "deck" structures, and construction of two further sections running alongside them was advanced, HS2 said.

The concrete, more than 2,000 cubic metres, was delivered and poured during night-time operations to minimise the impact on roads.

In total, over 11,000 cubic metres of concrete will need to be poured to complete the whole 300m (984ft)-long viaduct.

A total of 26 "piers" - up to 6m (20ft) tall and supporting the flat sections - have also been built, and four large "steel tripods" are being constructed to carry the viaduct over Digbeth Canal.

Next summer, the span over the canal will be completed.

HS2 stated there had been "huge progress", and work on Curzon Street station would start next year.
