The arches are part of Coventry's Phoenix Project to rebuild the central part of the city after the ravages of war. To quote designers Lusas, '...the arches are formed of aerofoil section tubular lattices, clad with perforated stainless steel sheathing. The arches are fabricated from standard circular hollow steel sections that span between plated diaphragms. One set of tubes span directly between the diaphragms to carry the axial thrusts and bending moments, another forms a series of spirals between the diaphragms and these carry the shear forces and torsions that exist under the different loadcases. The arches lean together supporting each other through a single connection point at the crown approximately 15m above the ground.'

The overall appearance is of sinuous blades which are hollow and resemble the fuselages of aircraft.
