The Dover to Folkestone railway line is set to reopen in the autumn.
The £39.9M project to rebuild the Dover to Folkestone line is nearing completion, following repair work which has been underway since December 2015.
Network Rail is building a 235m viaduct supported by 134 concrete columns to deal with severe damage to the line.
“This project has been a challenging one and normally a scheme of this size would take two years to design and build. We are very proud of everyone’s commitment to get this line open as soon as possible,” said Network Rail’s senior programme manager Steve Kilby.
