Work to replace the Loughor Viaduct near Swansea is complete

08 April 2013

One of the most exciting parts of the project, replacing the old Loughor Viaduct with a new bridge, has been completed, and we've also finished laying additional track at the former bottleneck through Gowerton.


Work began on 24 March 2013 and finished at 4am on 8 April 2013 ready for the early morning services, following a 16 day line closure so that our engineers could carry out extensive work to lay additional track, provide a new platform and footbridge, and upgrade Duffryn level crossing.

“The new viaduct and doubling the railway lines through Gowerton will remove the current bottleneck created by the stretch of single line and provide capacity to run more trains in the future.

This project joins a number of other rail improvement projects in South and West Wales that will help deliver better journeys and boost economic growth in the area.

The new viaduct and track at Loughor, as well as the new station platform and footbridge at Gowerton are part of a package of station and infrastructure improvements to make rail travel more comfortable. As well as making it easier to travel to and from West Wales, this work will help to boost local employment opportunities.”

Mark Langman, route managing director for Wales, Network Rail 

As well as the new viaduct and track, work also included:

  • A new footbridge
  • Bringing the old east-bound platform back into use
  • New lighting, signage and CCTV
  • Upgrading Duffyn level crossing
  • Additional work to structures at the River Lliw, Traffle Mill, Gypsy Cross and Rhosog
