(とても基本的な文章でありながら、伝えたいことを正しく伝えています。)
The road is blocked by snow. Diversions are in place.
When a road is closed for some reason, be it for repairs or natural causes, the authorities are usually quick to put in place appropriate signage and offer alternative routes for travellers known as 'diversions'.
EX: "You can't go down that road. It's closed due to snowfall."
何らかの理由で道路が通行止めのとき、工事、または地形的・気象的な要因によるもので、管轄局が素早く適切な標識を設置し、diversions（迂回路）を案内します。
例：
You can't go down that road. It's closed due to snowfall.
あの道を下りていけません。雪が降っているせいで通行止めです。
When heavy snow has blocked a road, vehicles can not be able to pass through. There is always a warning sign at the beginning of the road warning drivers wishing to travel along the affected road not to proceed because the road has been closed due to heavy snow. Such a warning is usually replicated on the radio and on TV. If a road is 'impassable', it means that it's impossible to travel along it.
So, you may say:
The highway is closed because of heavy snow.
or
The highway is impassable because of heavy snow.

When a highway is closed due to heavy snow, you can say:
-The highway/road is closed due to heavy snow.
-They closed the highway because of the snow.
"due to" and "because of" mean the same thing. You can also be specific by referring to the specific road/highway that is closed by saying "Mt Simon drive is closed due to heavy snow."
高速道路が大雪で通行止めの場合以下のように言うことができます。
-The highway/road is closed due to heavy snow.
高速道路は大雪のため通行止めになっています。
-They closed the highway because of the snow.
雪のため高速道路は通行止めになっています。
"due to" と "because of"はどちらも「〜のため」という意味です。
通りや高速道路の名前を入れてより具体的に言うこともできます。
