A popular footpath between Langlee and Tweedbank is to close for eight weeks from February 17 to allow repairs to be carried out on Redbridge Viaduct.
The work is linked to the reopening of the Borders Railway next year.
The bridge deck will be waterproofed and resurfaced, utilities will be moved and masonry repairs carried out before it is reopened in April. A footpath diversion via Galafoot Bridge will be in place for the duration of the job.
Work on the bridge will continue once the path reopens, with the walking route fenced off. Once the railway opens in autumn 2015, a footpath will be retained alongside the track.
Hugh Wark, Network Rail project director for Borders Railway, said: “We know that the Redbridge Viaduct link between Langlee and Tweedbank is an extremely popular walking and cycling route, and we’ve done all we can to retain that access until now.
“The improvements mean that this relatively short eight week closure is unavoidable – we apologise for the temporary inconvenience.
“The bridge itself is in excellent condition and the structural works required are minimal.
“Once complete, this grand old structure will form another iconic landmark on the Borders Railway route.”
Other key activities taking place throughout Galashiels and Tweedbank in the coming months include:
z Wheatlands Road: A new bridge will be built to carry trains over the road. Traffic management will be in place until October 2014 and the road will be closed when the bridge sections are lifted into place. Another bridge will be built over the Gala Water reusing existing bridge supports.
z Low Buckholm Road: ongoing drainage works, building of retaining walls and structures.
z Currie Road: A new bridge will be built to take trains ver Currie Road. Some road closures will be required when the bridge sections are lifted into place.
z Glenfield Road area: SBC is currently undertaking works as part of their flood protection scheme, with the rail project using this opportunity to undertake works in the area. Work will be finished by October 2014.
z Winston Road: Work to divert utilities is ongoing. Temporary works are being installed to allow for the construction of the new bridge which will carry the road over the railway. The road is estimated to reopen in October 2014.
