D-Day-style Solution for Hammersmith Bridge?

Proposed temporary bridge by Tim Beckett

According to a recent article in the Daily Mail, Shepherd's Bush author and journalist Robert Hardman has identified an imaginative solution to the perma-closure of Hammersmith Bridge - a "D-Day"-style steel replacement. 

The temporary bridge is the brainchild of marine engineer Tim Beckett and his team at Beckett Rankine, builders of harbours, bridges and piers.
