This picture shows a section of the Ruthven Bridge near Tomintoul which had 90 arch stones known as Voussoirs replaced in 2007. The whole bridge had an elaborate designed scaffold built under the barrel of the bridge to support the masonry as the Voussoirs were replaced. Each stone weighed approx quarter of a ton and were hand dressed on site to fit their individual positions. A strong Hydraulic lime mortar was used to fix them in situ and left to cure for 3 weeks before the wooden form support was taken away. The surrounding old masonry was re-pointed in a lime mortar to match the original traditional lime mortar.
