Set to be shut until 1600
Police now say the Mountain Road will remain shut until at least 4pm.
They'd previously said it would be open by 2pm - but persistent, heavy sleet and snow has forced officers to keep the route sealed - with a snow plow on standby for when conditions ease.
Gritters have also been out on other Island roads, including the Sloc Road and Creg ny Baa Back Road this morning.
A weather warning from the Met Office is forecasting continued adverse weather until the early hours of Thursday morning.
