Fifty years ago a road bridge across the River Garry in Perthshire was declared open. It offered a route from the A9 across the wilds of Rannoch Moor to the west, and was considered a minor engineering triumph — the first box girder bridge in the area, standing 40m above the river, built with pre-war machinery and a lot of back-breaking labour. Last weekend some of the men who worked on it came back to take part in a 50th anniversary celebration, and to marvel at what they had done. “It was hard work, we had to hand-drill for nine to ten hours a day — it would never be allowed today,” one of them, Bill Stewart, said. “But we’re proud of what we did.”
