On the big city walls that are in <abbr title="MegaMod">MM</abbr> (that I kind of gave up on) one of them has a culvert. It's a ghost piece that extends below ground level, so when it's placed over a river, you can see it. But if it's placed on normal ground, the culvert part is covered by the ground. Something similar may wor here, too.
