A crash involving a tractor and van on the A55 has left two men in hospital.
The collision on Friday involved an Autoglass van and a red and tractor which had been towing a trailer.
North Wales Police closed the eastbound carriageway for more than two hours after both vehicles overturned.
Two men were treated at the roadside before being taken to Ysbyty Glan Clwyd by land ambulance with what are thought to be minor injuries.
A Welsh Ambulance Service spokeswoman said: “An elderly man and an adult male were treated at the scene before being taken to Glan Clwyd Hospital, Bodelwyddan in a stable condition.”
A spokeswoman for the North Wales Fire and Rescue Service said: “We were called at 12.15pm to a road traffic collision on the A55 eastbound near St Asaph.
“We sent a crew from Rhyl and Holywell to the scene with reports of persons trapped.
“When we arrived one patient had been helped from his vehicle by police and no one else was trapped.
“We offered assistance to the other emergency services at the scene.”
One motorist told the Daily Post: “I was driving by on the westbound carriageway just before 1pm when I saw the crash scene.
“The air ambulance was parked at the front and there were two ambulances and two fire engines there and police.
“There was a farmyard trailer in the road and tractor which had flipped over and was facing the wrong way.
“A white transit van was also on its side and its side door was about 5ft away from it. The van was really badly damaged.
“It looked absolutely awful, I’ve seen a lot of crashes on this stretch but this looked bad. I really hope everyone is okay.
Another driver said: “We were stuck in miles and miles of tailbacks during the incident. There was a huge emergency service response in the area which was really worrying. Really hope that everyone has made it out okay.”
