Kutai Kartanegara Bridge
The Kutai Kartanegara Bridge (also known as the Mahakam II Bridge) is an arch bridge, formerly a suspension bridge, located in Kutai Kartanegara Regency, East Kalimantan, on the island of Borneo in Indonesia. It crosses the Mahakam River and connects Tenggarong and Tenggarong Seberang districts, as well as roads that lead to Samarinda. The  bridge, which featured a  suspended section, was intended to resemble San Francisco's Golden Gate Bridge. Construction on the bridge commenced in 1995 and was completed in 2001. It was the longest suspension bridge in Indonesia. On 26 November 2011, the bridge collapsed only ten years after it was completed, killing at least 20 people and injuring 39. The bridge was constructed by state-owned builders PT Hutama Karya at a cost of Rp 150 billion (US$16.4 million). Collapse

On 26 November 2011 at  9:59pm (local time), while workers were performing maintenance on the bridge, a support cable snapped and the structure suffered a catastrophic failure. The roadway fell into the  Mahakam River below, leaving only the two bridge towers and some support cables remaining. At least 20 people were killed and 40 were injured, with an additional 19 people reported missing. A replacement arch bridge was built in 2013 and formally opened in December 2015. References
