The company building Britain’s high-speed railway project, HS2 Limited, has revealed designs for the viaduct that will span the 150-metre section on final approach to Birmingham’s new Curzon Street Station. The bridge design features a 25-metre-high central truss, which the company says will create a new icon on the city skyline. The superstructure will be illuminated by a visual art installation conceived by Glasgow-trained Liz West.
