A lorry driver has died after crashing into a motorway central reservation barrier in Dumfries and Galloway.
The northbound articulated lorry hit the barrier on the A74(M) south of Lockerbie , at Junction 20, and left the road just after 5.45am on Monday.
Both carriageways were closed as emergency services recovered the vehicle, with a crash scene investigation taking place.
The southbound carriageway reopened around midday but the northbound carriageway remained shut.
Inspector Campbell Moffat said: "We are appealing to anyone who may have been on the A74(M) motorway this morning to get in touch if they saw this crash.
"We would also be keen to hear from anyone who may have captured any dashcam footage of the crash, or the northbound lorry just prior to the crash.
"Anyone with any information should call police on the 101 number and quote the reference number 0454 25 November 2019."
A second incident happened near the same junction at 10.05am, with a van driver in a critical condition in hospital after crashing with a lorry near Eaglesfield.
The 34-year-old driver of the Renault Trafic van was taken by air ambulance to the Queen Elizabeth University Hospital in Glasgow.
The lorry driver was uninjured.
Officers are appealing for any witnesses to the crash, or anyone who has dashcam footage to contact 101, quoting reference number 0926 of 25th November.
