Koror–Babeldaob Bridge

They concluded that the bridge was "safe" as of now (in 100 year increments it will cave in 90 cm) and the large deflections were due to creep and the modulus of elasticity of the concrete in place being lower than anticipated.

By request of Kuniwo Nakamura, then the country's President and foreign minister, Japan provided emergency aid as well as a temporary bridge.

The failure occurred during benign weather and loading conditions, six years after two independent teams (Louis Berger International and the Japan international Co-operation Agency[6]) of bridge engineers had evaluated the bridge and declared it safe, and less than three months after completion of a strengthening programme to correct a significant midspan sag that was continuing to worsen.

Based on the studies, the Palau government decided to counteract the cosmetic damage caused by creep with resurfacing and reinforcement of the bridge.

[10][9] The repair and resurfacing operation may have contributed to the bridge failure, but since the lawsuit over the collapse was settled out of court[citation needed], no final cause has ever been definitively published.

As the Palau government lacked sufficient funds to rebuild immediately, a new bridge to provide a steady transportation system was constructed with significant Japanese Grant Aid in ODA.
