Ahhh...the signs were not posted properly.
The Ever Forward, a 1,095-foot ship that weighs around 130,000 tonnes, is currently stuck off Pasadena, Maryland after running aground between the US cities of Baltimore and Norfolk. It is understood that the ship had around 5,000 containers on it when it ran aground.
According to NPR, it apparently missed a turn when leaving Baltimore that caused it to end up in the shallow waters of Pasadena, where it has remained for three weeks.
NPR also reported that while the ship needs a depth of 42 feet of water to operate, it had only 24 feet, leaving it buried in about fifteen feet of mud.
