this is from one of our detested yank news sites - but, it's irrelevant where from
it's also just an idea which should make us think about something completely different in Australia
when one reads it - think about dutto the magnificient's idea of planting nukes in old coal stations ----------- because he thinks it's a great way to save money ------ by using 50 year old power lines -
now, think about that when you read this
''A deadly bridge collapse in Baltimore. A bridge in southern China sliced in half. Parts of a bridge cutting through the hull of a massive ship in Argentina.
These events all happened within the first three months of this year – and all after collisions with large commercial ships.
These incidents, and the toll – with at least five killed in China, and six still missing in Baltimore – have highlighted what experts say is the urgent need to improve or protect old bridges to accommodate larger modern vessels.
The Baltimore collapse on Tuesday focused national attention on the issue, after a large container ship lost power and crashed into the Francis Scott Key Bridge, sending people and vehicles into the frigid Patapsco River.
“We need to remember this bridge was built 50 years ago, and the ships at the time were a fraction of the size of what DALI (the ship that crashed) is today,” said Sal Mercogliano, a former merchant mariner and maritime expert.
“And DALI isn’t even a big container ship, there are much larger vessels that are out there,” he added. “So in many ways we have infrastructure that was built for another time.”
