The first of two giant steel girders was recently delivered to the Hinkley Point C nuclear power station site in Somerset.
The beam travelled from Avonmouth to nearby Combwich by barge before making the final part of its journey by road
The steel beams, each spanning the width of a football pitch, are the longest structural components that will be used on the project.
They will support the 300-tonne overhead crane as it manoeuvres on rails up and down the turbine hall.
