Yahoo! News - Urine may lead to collapse of major bridge in Indonesia's Sumatra.

Public works officials have found that the Ampera bridge, the landmark of Palembang city, the capital of South Sumatra province, has begun to lean on an angle and rocks slightly when traffic is heavy, the Jakarta Post said.

An official at the public works department in Palembang, Azmi Lakoni, was quoted as saying the bridge had deteriorated because people often took a leak on one of its piers, corroding the structure.
