Sosrobahu

Elevated toll road on Jalan Ahmad Yani by pass, Jakarta, Indonesia. The elevated road used the Sosrobahu construction technique that rotates the beam-supporting bar on each pylon.

Sosrobahu is a road construction technique that allows long stretches of flyovers to be constructed above existing major roads with minimum disruption to traffic. The technique was designed by Indonesian engineer Tjokorda Raka Sukawati and involves the construction of the horizontal supports for the highway beside the existing road, which are then lifted and turned 90 degrees before being placed on the top of the vertical supports to form the flyover pylons.[1]

The term Sosrobahu was derived from Old Javanese; it means "thousand shoulders".[2]
