The HS2 railway then moves into a tunnel emerging east of the A452, before heading south at Castle Vale towards London.  Within Birmingham, we will be building one tunnel at Bromford, two viaducts at Saltley and the River Tame, and a major depot at Washwood Heath. Three more viaducts through Digbeth and the new HS2 Curzon Street Station will also be constructed.  #hs2
