Leith Street Bridge, Edinburgh

Broadway Malyan – Project

Broadway Malyan Architects are working on proposals for Princes Street in 2004-2006

Leith Street Bridge
Architects Broadway Malyan have announced that planning permission has been granted for a landmark pedestrian bridge linking St James shopping centre to Calton Hill across Leith Street, Edinburgh. The pedestrian bridge link and terminal building are constructed from glass and a distinctive interlocking helical steel frame. The bridge will provide spectacular views of the City and of Calton Hill. The scheme integrates with the new Nottingham Terminal, located next to Pillar’s Calton Square / Omni edinburghdevelopment.

It is due to open in August 2002.

Broadway Malyan’s Edinburgh bridge is ‘S’ shaped in plan and constructed from circular hollow sections of steel that interlock to form a helix. Six longitudinal tubes are provided to act as top and bottom chord elements. Ring diaphragms will stiffen the support positions within the superstructure. The basic structure could be described as a space frame, which is crudely a complex composite beam that spans 46m over a dual carriageway in the heart of Edinburgh City centre.

The Leith Street bridge has glass parapets designed to P4 containment standards and has a glass roof incorporating a central aluminium rainwater drainage channel. The bridge deck is constructed from lightweight interlocking extruded aluminium planks and is illuminated from light fittings at deck level. The bridge supports are tubular members in a ‘V’ shape configuration with cross bracing between parallel supports, which are bolted down to concrete columns.

The bridge is 50m long and weighs 90 tons. The pile foundations are 25m long founded on bedrock. The foundations at each end of the bridge are divided by a fault line, which runs straight down the middle of the dual carriageway.

The bridge has been designed to move +/- 15mm and has a camber of 1 in 100 from the middle of the bridge down to each end. The camber not only provides the gradient required for bridge drainage system but also is designed to deceive the human eye into reading the bridge as perfectly flat against the horizon.

If all the circular hollow tubes were straightened out placed end to end they would stretch for nearly a mile, 1.4 kilometres!
