In my area, planned road closures and maintenance are published in the paper. I'm not sure there's a "standard" way this would get to an AV, e.g. a public API with a specific protocol for this sort of thing. Maybe it can tap into Waze info somehow? And in case of disabled vehicles, accident cleanup, or other unplanned lane closures, sometimes the cones are just set out and you don't know anything about it in advance.
