No conspiracy talk please.
The ship had a catastrophic electrical power failure as it approached the bridge. Wind and tide caused a radical and uncontrolled change of course (see last two Suez canal accidents).
Key Bridge was very old and under constant repair every day for at least the last 30yrs.
It could not have been a better time for the worst to happen. Hour and a half before rush hour. Casualties should be light. Mostly from bridge repair crews.
@Render Actual information from a decent source. Thank you.
I expect the last of the debris to cleared sometime between the middle of June and the middle of July this Summer.
Until then the old port at Sparrows Point could (and should) be brought back into at least temporary service. It would obviously not be an entire replacement for the terminals north of the bridge but would suffice in the short term and can be done in about a months time.
Rebuilding the bridge itself will probably take a minimum of 2yrs.
