A busy bridge collapsed Saturday in central Indonesia, killing at least three people and injuring 17 others as a bus, cars and motorcycles crashed into the river below, police and witnesses said. The sprawling, 770-yard (700-meter) bridge built to resemble the Golden Gate Bridge in San Francisco linked the towns of Tenggarong and Samarinda in East Kalimantan province. It was clogged with traffic when the accident occurred, Syaiful, a witness, told local television station TVOne. He saw at least one bus and close to a dozen motorcycles plunge into the Mahakam river. Several cars were mangled. Everyone was screaming, said Syaiful, who like many Indonesians uses only one name.
