Hackney Wick Station And The Florida International University Pedestrian Bridge Collapse

The title of this post might seem a bit unusual, as the two locations are in different continents and thousands of miles apart.

But there is a connection, in that the new Hackney Wick station and the Florida International University bridge, were built using the same construction method called accelerated bridge construction.

There are some major differences.

  • At Hackney Wick a short, fat subway was built alongside the railway and moved in using self-propelled modular transporters. In Florida a long thin span was installed , in a similar way.
  • The Hackney Wick station subway, probably weighs a lot more than the pedestrian footbridge.
  • The Hackney Wick subway and the platforms and track on top, was fully reinstated before trains could cross, whereas the Florida span was part of a cable-stay bridge, which hadn’t been completed.
  • The Hackney Wick subway will be carrying trains of several hundred tons, whereas the Florida bridge will be carrying people.

It looks to me, that there has been some inaccurate calculations, which led to the collapse of the Florida International University bridge.
