<p>The construction of the Pulau Poh cable-stayed bridge has been challenging both technically and environmentally. The curved pylon shape in two planes, with changing cross section and heavily congested reinforcement pose constructability concerns. Accurate geometry control and positioning of stay cable anchorages within the pylon is crucial to ensure the bridge meets its intended design life. Located in an area with high rainfall intensity presents additional environmental challenges, where working areas are constantly submerged. To address the challenges and meet the project deadline, innovative construction methodologies are being adopted. The bridge design was also revisited, taking into consideration the construction approach. This paper aims to explain the challenges faced and methods used to fast track the construction of the Pulau Poh cable-stayed bridge.</p>

Harp shaped cable-stayed bridges without backstays are popular due to their beautiful and unique styles; they employ leaning tower columns to balance the constant and movable loads on the decks and are not provided with backstays, so they are beyond the traditional bridge design philosophy. In this paper, we discussed the reasonable structure of the main girder of Changsha Hongshan Bridge – a harp shaped cable-stayed bridge without backstays through changing the design parameters of the main girder in respect of design so as to provide important reference for design of this kind of bridges, and the research mainly related to such aspects as the structure selection for and section design of the main girder, the influence of overweight of main girder on the force on the structure, the length of non-cable area of the main girder, the span of auxiliary hole, etc.
