The Department of Infrastructure says the road from the Creg Ny Baa Hotel to Hillberry has now reopened to traffic.
On Facebook, it says the route, along with the Creg ny Baa Back Road, has been treated with salt and is now passable with care.
However, the Mountain Road itself remains closed from Ramsey to the Cregy ny Baa.
The DOI says it'll review the situation tomorrow morning.
