A single span 50m long prestressed road bridge has been fabricated under a Public Works Department contract in the State of Negeri Sembilan, Malaysia. The bridge, across a river, was constructed at the small village of Kampung Linsum, Sungai Linggi. To date, this bridge is the first in Malaysia and may also be the world's longest composite road bridge made from ultra-high performance ductile concrete (UHPdC). This paper presents the features of the UHPdC precast girder; gives a brief insight into the manufacturing process of the girder; highlights the bridge's construction sequence; illustrates the design method and provides an environmental impact calculation. The midspan deflections of the bridge at different times in its construction history were compared against the collected field data and these figures showed that the calculated values were in general in agreement with the field data.
