The Port of Baltimore does not even have an oil handling facility, never mind the fact it could not admit a VLCC even if it had cause to.

Even ports on the US Gulf Coast do not generally have the capability to dock VLCCs.

If Baltimore had been anticipating VLCC traffic in the 70s, then presumably the bridge would have been built accordingly and this incident would not have led to a collapse.
