SUNGAI DINDING BRIDGE, LUMUT PERAK, MALAYSIA

The Sungai Dinding bridge, recognised as a landmark structure in Malaysia, has a 930m long central multispan arch bridge with a 653m approach span on one side and 248m viaduct on the other. The main bridge arching across Sg. Dinding, was built with temporary stays and a steel/concrete composite deck on top. Two allied bridges across Sg. Setiawan and Sg. Tebuk Raja Samalon take the form of incrementally launched box girders. The official name of the bridge is Jambatan Raja Pemaisuri Bainun, named after Tuanku Bainun of Perak.

HSS was engaged to provide structural engineering design check and review of the geotechnical design. This was one of the unique bridge designs in Malaysia. The bridge after construction is to be an arch bridge, but in order to built the arches, cable stay designs were involved during the construction phase.
