The K.H. Noer Ali Fly-Over in Sumarecon – Bekasi: Efficient Infrastructures with DYWIDAG Tendons
Like many other cities in Asia, the Indonesian city of Bekasi east of Jakarta is dealing with an ever increasing traffic volume. Recently, a new flyover was built there as an important infrastructure enhancement that provides a better connection of the city center to the east and to the modern district of Summarecon.
Named after the Indonesian independence patriot from the city of Bekasi, K.H. Noer Ali, this fly-over, opened for the public on April 13th 2013, is an east-south connection in Bekasi that leads over the main station. The elevated road is approx. 1km long and 22m wide and consists of approx. 724m long access ramps as well as a bridge structure consisting of a 130m long main span and two 73m long side spans. The side spans consist of a simple continuous prestressed concrete girder and the main span is a balanced cantilever two cell hollow box girder bridge. This project is one of the first two cell box girder bridges in Indonesia.
To post-tension the continuous prestressed concrete girder and the hollow box girder, DSI licensee PT Delta Systech Indonesia supplied and installed 650t of DYWIDAG Strand Tendons with Type MA 6819, MA 5912 and MA 5919 Anchorages. Furthermore, PT Delta cooperated with DYWITECH Co. Ltd., Taiwan, to supply and operate the DYWIDAG Form Travelers.
