A couple had to spend their wedding night stuck in a school on the edge of Dartmoor after the snow hit.
Newlyweds, John and Sara Lund, were making their way from their Bristol wedding to a hotel in Newquay when the road became impassable.
The A30 was hit by "significant snow" overnight, Devon and Cornwall Police said, with conditions "changing rapidly".
After being rescued from their car, they joined over 80 other people staying overnight at Okehampton College which was acting as a temporary shelter.
Mr Lund said "The lovely people of Devon County Council have looked after us very well.
"I didn't imagine there would be snow in March to be perfectly honest with you, but certainly didn't expect to spend our first night in a school college."
The road reopened this morning at around 8am after being closed on Sunday evening and overnight.
The couple said they hoped to continue their journey to the hotel, where they are booked in for three nights.
