I wonder what the AI was trying to accomplish with this road (besides just wasting ).
Nope. In fact, you can't even destroy it. Every improvement built outside the territory can not be destroyed and costs no maintenance.Do you pay for road maintence on roads outside your borders though?
Not quite accurate. If you build a road in no-man's land, you pay maintenance and you can destroy the road. If you build a road in someone else's land, they pay maintenance. if you stumble across a road in no-man's land that someone else built, you cannot destroy it. if your culture borders later expand to include that road segment, you start paying maintenance and can destroy the road.
SIGH....... You are playing Brave New World.... You build roads in the open to extend the range of your land trade routes.
That's strange, I was sure I didn't pay anything. Should check it...If you build a road in no-man's land, you pay maintenance and you can destroy the road
