It is 38 mins long (2.5 min version also available) in four sequences (no sound):

Sequence One. - 14 to 18 April, (18 mins duration). The first view shows the beams being assembled in the compound, the main crane being rigged and (go to 10 mins) on Saturday 18 April the beam pairs being lifted on to the eastern piers.

Sequence Two - 24 and 25 April (go to 18 mins, 11 mins duration). The view shows the A47 closed to traffic, with the arrival and rigging of the main crane (go to 19 mins), arrival of the first beams (go to 23 mins) followed by lifting on to the western piers.

Sequence Three – 9 May (go to 29 mins). A fresh view shows central span beams being lifted into place and the de-rigging of the crane to move to the other side of the bridge for the final two lifts.

Sequence Four – 9 and 10 May (go to 33mins 40 secs). The view moves to the other side of the bridge, showing the crane being rigged and carrying out the final two lifts (the lens is foggy briefly.)
