ALEXANDRA LINK

Alexandra Link is a unique three-quarter suspension bridge which is supported from inclined columns at only one road end and suspended from two main inclined cables. The tension forces in the suspension cables are resisted internally by compression through the deck of the bridge. This allows a dramatic reduction in foundation requirements by carrying all the horizontal forces caused by the cable tension internally within the bridge structure, rather than anchoring the loads to external foundations.

HENDERSON CROSSING

The curved approaches of Henderson Crossing are supported from the arch and have one intermediate support before the landing at each hillside. The curved approaches are out of plane with the main arch and this geometry is utilized to brace the arch against lateral out-of-plane loadings. The arch and intermediate supports of the curved approaches form a tripod support to the structure, which is stable and strong.

SOUTHERN RIDGE BRIDGE DESIGN COMPETITION

A design competition was launched by Urban Redevelopment Authority (URA) to find quality designs for two bridges, Henderson Crossing and Alexandra Link, to link the three hill parks: Mount Faber Park, Telok Blangah Hill Park and Alexandra Park at the Southern Ridges.

There were 65 submissions for this competition, with 11 from countries like the USA, the UK, Japan, South Korea and China. We are proud to be one of the winners to receive the merit awards given out to five schemes which stood out.
