The incident took place in Regent Street, Leeds as contractors worked on the A64 bridge replacement works that will see a new £31million flyover installed in the city centre.
A section of the newly demolished bridge managed to destroy a truck below it as concrete chunks were being moved onto the back of a specialised vehicle yesterday evening.
