SECTOR SNAPSHOT Ӏ BRIDGES


before being slid into position in just three days, reaching the north abutment on Friday 20th June. During the slide pads covered in


PTFE - a Teflon-like material usually found on the surface of a non-stick frying pan - were used to minimise friction between the deck and the temporary steel bearings on top of each of the five concrete piers.


It is the last of five viaducts being built using this technique by HS2’s main works contractor responsible for the central section of the new railway, EKFB - a team made up of Eiffage, Kier, Ferrovial Construction and BAM Nuttall – working with specialists at Eiffage Metal. With the steelwork now in position,


engineers can begin the next stage of the operation, lowering the deck 60cm onto


the permanent bearings before work on the concrete deck and parapets can begin.


EKFB is delivering 15 major viaducts


for HS2 between the Chilterns and South Warwickshire. Lower Thorpe is the last of five that are being slid into position. A video of the viaduct installation can be seen here: www.youtube.com/ watch?v=iEV1ARbDKZc
