Network Rail has confirmed that the B710 road between Bowland and Clovenfords is to close for approximately five months
The closure is to allow a new bridge to be constructed at Bowland north of Galashiels for the multi-million pound Borders Railway.
Network Rail’s project director Hugh Wark said the bridge was strategically important and closure was unavoidable.
He added: “The project team understands how important the road is to the local community and we will endeavour to complete the work as quickly as possible to limit the inconvenience to local residents.
The C11 Ferniehurst road which is currently closed will re-open before the B710 closes on April 7.
