Just had a couple of simple queries.
1. Are there routing issues in placing two roads running alongside each other with no gap in between (but not overlapping).
2. Can bridges be effectively used as tunnels, since they have their own routing that overrides other routing data such as non routable terrain. For example instead of digging a river downwards, raise a hill upwards and add decorative tunnel ends from WA? Would sims follow the bridge's routing data and travel through the terrain/obstacles?
