Do Yandex-maps know ferry crossings, winter roads and glaciers in Russia?

Question

API

To calculate freight transport routes, you need to know seasonal routes (winter roads, glaciers) and ferry crossings. Can Yandex do it? If not Yandex, then who?

Answer 1

Not sure. At the weekend we went to Dubna, there is a crossing there. He just built a route, like over a bridge.

Answer 2

he knows nothing about winter roads, since he is not in demand by anyone.

Answer 3

no one knows this for Russia. There is a lot of information in OSM, but again it depends on the region. And why do you need it? if it `s not a secret
