Location

The Seri Wawasan Bridge is one of the main bridges in the planned city Putrajaya, the new (2001) Malaysian federal territory and administrative centre. This futuristic asymmetric cable-stayed bridge with a forward-inclined pylon has a sailing ship appearance, accented at night with changeable color lighting. The bridge, also called Bridge No. 9,^[1] crosses Putrajaya Lake, an artificial lake made to provide natural cooling, and connects Precinct 2 on the Core Island, where the main government buildings are located, to the residential area of Precinct 8, 9.^[2]

Structure

[edit]

The Seri Wawasan Bridge is a longitudinally asymmetric cable‐stayed box-girder bridge with an inverted-Y shape concrete/steel pylon 96 metres (315 ft) high. The main span, 165 metres (541 ft) long, is supported by 30 pairs of forward stay cables, anchored on the 75° forward‐inclined pylon and on the outer edges of the bridge deck, arranged in a fan shape pattern from the side elevation. To counterbalance these front stays, a combination of 21 pairs of cable backstays and structural steel tie back was used. The back stay anchored at the (next-) highest point of the pylon is anchored at the curved backstay anchorage point (next-) nearest to the pylon, creating a crisscross‐over pattern from the side elevation,^[3] which adds to the aesthetic of the bridge. The overall complexity of the back stay tie back structure, however, may be aesthetically distracting.^[4] The inclined concrete pylon and the backstays are anchored into bore piled foundation off the roadway in precinct 8.

The bridge carries a dual three lane carriageways of 18.6 m width each, comprising 3 x 3.5 m width lanes, 0.5 m hard shoulder, 0.5 m marginal strip. The median is 4 m wide and walkway cum cycle track width is 5.1 m giving a total width of 37.2 metres (122 ft) at the centre of the bridge.
