Should the type of bridge be used to designate toll bridges? Or should this be captured elsewhere with a another more generic location type? I couldn't find any existing schema for tolls/fees on roads and bridges in my quick and cursory search today.
I would think that the bridge type would be the place to store toll-bridge info (and similarly the road type the place for toll-road info). The other option would be a new "toll-bridge" type, but that probably wouldn't be necessary.
