One of the longest bridges in northern China collapsed on Friday, just nine months after it opened, triggering a storm of criticism from Chinese Internet users and underscoring questions about the quality of construction in China’s rapid expansion of its infrastructure.

A nearly 330-foot-long section of a ramp of the eight-lane Yangmingtan Bridge in the city of Harbin dropped 100 feet to the ground. Four trucks plummeted with it, resulting in three deaths and five injuries.
