Trabzon and Constantinople have no road connection ?

[Shahed]

OK thanks. That's really le suck.

To move troops from Caesarea to Constantinople it appears the fastest route is through Trabzon, without a road connection. So the army goes over land. There is a strip next to the coast that could have a road, there is also a long valley which could have a road. Nonsensical it seems, not to have one.
