Network Rail engineers who are working '24/7' to fix the Nuneham Viaduct have issued an update on their progress.

In a video shared to Twitter they say piles have gone into the river bed. This will allow them to build a structure which will support the viaduct so they can remove the abutment.

The bridge carrying the main railway line from Didcot to Oxford was closed on April 3 after ‘significant movement’ was detected in the viaduct’s structure.

The line will not reopen until early June.

Engineers had been carrying out ‘stablising works’ in the previous few weeks but a rapid and unexpected deterioration saw large cracks appear in the bridge which crosses the River Thames between Culham and Radley.

Network Rail repeated that its engineering teams were working ‘round the clock’.

Rail replacement services are currently running between Didcot and Oxford.
