Devon Place Footbridge


Alun Griffiths for Newport City Council

Project Description

Devon Place footbridge is a new structure spanning over Newport Railway Station to replace the original subway connecting Devon Place with Queensway.
The new structure is formed from two half through bridge structures crossing the railway with inclined faces with curved continuous ramps leading down to ground level. The position of the structure was dictated by the current station infrastructure – including basements, subway, canopy & platform and space to provide the necessary ramp lengths to satisfy clearance requirement to the electrified railway.
Works also included the new public realm space at Queensway.
