City Development: Riverhold

This is the official thread for the development of Riverhold. All ideas are welcome as long as they are lore-friendly and possible within reason.

I would like Riverhold to obviously be along a river. Maybe two sides of the river. There could also be an awesome platform that spans the river and part of the city is built on it. This gives me an idea. The city could have like a water gate. (not really a dam though)

I think THIS one could be wooden. Could someone scrutinize the lore to be sure? I would like to have some buildings on the banks of the river but I'd like to have the river wide enough to warrant a nice bridge that could hold the main part of the city. Y'know, like SKYRIM's Solitude but on an artificial bridge and not so stupid.
