Concrete mixer problem

[Shaney!]

So I am trying to construct some buildings using the construction office, however the concrete mixer can not reach the construction site.

The concrete mixer moves to the concrete plant, loads up and then gets a question marker above it. This usually indicates that the vehicle can not get to the next stop (the construction site). However, the construction site is connected both through road and paths, and the workers arrived by bus just fine. Am I missing something?

Screenshot please. Most common cause is there is a tiny piece of missing road in front of the construction site.

In my experience, you can usually trust the auto-assignment order of construction offices, they will build the little pieces of missing road infrastructure before building the things on the other side.

I guess it is caused 4x distance optimization. Probably the distance from concrete plant to construction site on the road is 4x longer than distance by the air.

It'd posssible too, that the mixer can't reach his destination, because the entrance there isn't ready yet... The construction offices sometimes send vehicles to places they aren't reachable yet.
Try to cancel the assignment in the responsibly construction office and check if all ways to your construction already built.
