Koom Gorge Bridge
From Discworld MUD Wiki
The Koom Gorge Bridge is a stone bridge on the Genua road over the Koom River, 7 miles east of where the road junctions with the Koom Pass road and the Koom road. There is an ancient, weathered sign east of the bridge that marks the "Future site of Ham-on-Koom". Since the bridge is surrounded by Plains, it does not appear to be in the Koom Gorge itself, but just outside of the gorge.
