Redbridge Viaduct Maintenance Work

Redbridge Viaduct Maintenance Work

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


We understand that you will have questions about the work we are doing and we have tried to answer those below.

If the answer to your query is not below, please use our contact form to share your question with the project team and they will come back to you.

  • What are you doing at Redbridge Viaduct?

    Our work involves masonry and scour repairs at the base of four of the viaduct’s piers.

    Scour protection work involves the removal of the existing riverbed around the impacted area of the piers and then the installation of a scour mattress. This will help to protect the base of the structure from scour erosion in the future, which is caused by fast flowing water.

    On completion of the mattress installation, the existing riverbed will be reinstated to the original level.

  • When is this going to happen?

    The work is being delivered in three phases from April until October 2021.

    The first phase will be at the west side of the viaduct, where activity will concentrate on repairs to the base of the first pier.

    Work will be daytime only, from 7.30am until 7pm each day, including weekends.

    We will provide updates on phases two and three as work progresses.

  • Why is this work happening?

    We are carrying out this maintenance work as part of our commitment to a safer railway.

    Our work will make the structure stronger and better protected against scour erosion.

  • Will this work impact on access to the public footpath under the viaduct?

    The public footpath that runs parallel with the river and under the viaduct will remain open at all times, with a short diversion in place between May and September.

    No traffic management is required during delivery of the project.

  • Will the work impact on train services between Tweedbank and Galashiels stations?

    No - as the work takes place underneath the viaduct, this will not impact on train services for the duration of the project and they will operate as normal.

  • Will there be an increase in noise levels while work is ongoing?

    While some of the plant and machinery we use may generate some noise, the impact of this should be minimal to the local community, given the majority of the work is taking place beneath the viaduct.

  • How is the work carried out?

    To allow our team to work safely, a portable dam system will be set up to reduce the river flow and create a manageable working area at each pier, with the team working from within a dry, protected area.

  • Will fish need to be removed from the protected area before you set up the dam?

    Ahead of setting up the portable dam at each pier, we will work with the River Tweed Commission to sensitively remove fish to another part of the river before the proposed dry area is dewatered.

  • How can I make an enquiry about the works?
