Police cleared traffic and pedestrians from bridge as cargo ship went nearly full throttle through South Carolina harbor

A large cargo ship lost control of its engines and went nearly full throttle through a South Carolina harbor prompting the closure of one of the busiest bridges in the state.

The incident comes after an out-of-control cargo ship smashed into the Francis Scott Key Bridge in Baltimore on 26 March after losing power, bringing the span down and killing six construction workers.

Harbor pilots in Charleston on Wednesday were able to help the nearly 1,000ft (300-meter) ship, which was going nearly 20mph (32km/h), get under the Ravenel Bridge safely and eventually anchor several miles offshore while the Coast Guard investigates, said Randy Preston, commander of the US Coast Guard’s Charleston section.
