There are currently two crossings of the river that is closest to Sanctuary. One is where the ruins of a bridge was found, it’s the closest to the city. The Travelers of Sanctuary have rigged a wooden skiff that’s anchored on both sides of the river by ropes to span the crossing.
Who made the bridge that is now only two large towers on either side of the span is still a mystery. The Petra family has studied the craftsmanship and says it’s superb and that the stone used doesn’t look to come out of the local limestone.
The other crossing over the river is an area of shallows farther up river than the bridge. It’s a small area that is mostly rapids. The river thins to merely a stream here to fit between two large hills. The Elders have seen fit to have a small fort constructed on the Sanctuary side on top of the hill overlooking this area, 5 Sanctuary guards man the fort and patrol the river.
