Bridge collapse hanger probed

Indonesian officials have confirmed that their investigation into the catastrophic suspension bridge collapse in East Borneo is focusing on the failure of a hanger connection at the deck.

No timeframe for report

Indonesia’s public works minister Djoko Kirmanto is leading the investigation.

“The weakest component of the bridge was the connection between the wire hanger and main deck,” Kirmanto told ministers.

A suspension bridge expert told NCE last week that this connection between the hanger and truss would likely be the key area to be investigated (News last week).

Along with the ministry, three Indonesian universities − Bandung Institute of Technology, Jakarta’s University of Indonesia and Yogyakarta’s Gadjah Mada University − will be working on the investigation.

Kirmanto insisted any recommendations arising from the investigation will be acted upon.

“After the results of these studies exist, then we should follow whatever the outcome,” added Kirmanto.
No timeframe has yet been given for when the investigators’ report will be published.

The three-span steel truss deck, with a main span of 270m, crashed into the River Mahakam in the East Kalimanta province late last month, leaving only the bridge cables and towers in place.

Bridge construction began in 1996 and finished in 2001.

The death toll from the collapse this week rose from 12 to 40. Nineteen people are still missing following the accident.
