Redbridge Viaduct Maintenance Work

Redbridge Viaduct Maintenance Work

A £2.4 million programme of essential repair work to Redbridge Viaduct in the Scottish Borders.

As part of Network Rail’s on-going commitment to maintain the railway infrastructure, we are undertaking a six-month programme of work to Redbridge Viaduct, located over the River Tweed on the Borders Railway line between Tweedbank and Galashiels.

The work is to undertake masonry repairs and provide scour protection measures to the base of four piers of the viaduct. This is to protect the Listed structure’s foundations against any further erosion and the work will be delivered in three phases.

The first phase of the work starts from the beginning of May until the summer and will concentrate on the pier at the west side of the viaduct, with work on the remaining ones following on from this.

Project Timeline

  1. April 19, 2021: Site set up and mobilisation
  2. May - June 2021: Work to pier one
  3. June - September 2021: Work to piers two, three and four
  4. October 2021: Work completes


Along with our contractor STORY, we will be delivering this essential maintenance work to carry out masonry and scour repairs to the piers of the Listed stone structure.

What will change?

Scour repairs involve the removal of the riverbed material from between the piers and a scour mattress will be installed to protect the piers from fast flowing water. Following installation of the mattress, the original riverbed material will then be reinstated to the original level.

To allow our team to work safely, a portable dam system will be used to reduce the river flow and create a manageable working area at each pier.
