An empty cargo vessel hit abridge under construction near the eastern seaport of Ningbo, Zhejiang Province, leaving four crew members missing.
The vessel collided with part of the lower span of the Jintang Bridge in Ningbo at 1:15 a.m., causing the collapse of a 60-meter-long section that fell onto the ship.
Sixteen of the 20 crew on board had been rescued by 7am. But rescuers were still searching for the four missing.
Officials speculated that the missing crew members might have been trapped in the cabin by the 3,000-ton collapsed section.
