Work to deliver one of the most challenging sections of the Borders Railway at Falahill will get under way next week.
The design, approved by Scottish Borders Council in November, moves the A7 which runs between Edinburgh and Galashiels slightly to the west of its current alignment, giving more room. It will also see a new bridge carrying the road over the railway.
The bridge is the third and final A7 crossing and will take the Borders Railway one step closer to bringing train services back to Midlothian and the Scottish Borders for the first time in 40 years.
During construction, a temporary two-lane diversion is being built to the east of the A7. Traffic lights will be required during later phases of the work, which is expected to last until the summer.
