Motorists reported white-out conditions, as snow and ice brought chaos to Cumbrian roads.
Earlier, Cumbria County Council's gritting teams said the A66 was closed in both directions between the Brough and Bowes junctions because of snow.
Gazfisher1000 on Instagram posted this video of the conditions earlier this afternoon but they have deteriorated significantly since then.
The team later announced that Hartside had also closed because of snow.
The A686 road leads up the Pennines between Melmerby and Alston, and is a known spot for snow.
In many cases it is not the volume of snow causing the issues, but the strong winds causing drifts.
A yellow warning of snow had been put in place last night by the Met Office, but was lifted this morning.
ROAD CLOSED :

Some motorists have reported blizzard-like conditions on Cumbria's higher routes.
Weather is thought to have been the cause of a jack-knifed lorry between Brough and Bowes earlier this evening.
