A 116-year-old bridge was demolished and replaced in less than 20 hours by Network Rail, timelapse footage shows.
It shows Awsworth Road bridge in Derbyshire – which carries around 5,000 vehicles per day – being lifted and removed before a new bridge deck is manoeuvred into place.
Timber decks were laid over the tracks before the bridge switch took place, when three self-propelled modular transporters (SPMTs) – which were all linked to a single operator – were used to take the old bridge away.
The original abutments were then lowered to make way for the new bridge deck while the old steel deck supports were removed, as the new bridge does not need them.
Two SPMTs then moved the new 33m long 500t concrete and steel bridge deck into place. It has a design life of more than 100 years.
The £3M project will be fully complete by the end of April and is part of a wider Network Rail railway upgrade programme in the Ilkeston area.
