A motorist has died after colliding with a lorry while driving on the M4 in South Gloucestershire.
Emergency services were called to reports of a crash involving a blue Tesla and a lorry on the eastbound side of the motorway between junctions 22 (M49) and 21 (M48) at around 4:30am on Monday 4 December.
The male driver of the Tesla was declared dead at the scene. His next of kin have been informed and are being supported by a specially trained officer.
No one else involved in the collision suffered any injuries.
The M4 was closed in both directions between the two junctions to allow investigations to take place and for the vehicles to be recovered.
Avon and Somerset Police wrote on social media: "Emergency services are at a serious injury collision which has fully closed the M4 between the M4 Prince of Wales Bridge (jnc 22) and Awkley (jnc 21)."
"The Greenditch Street overbridge is also closed following the earlier collision on the M4 which involves a car and a lorry.
"Please avoid the area."
But the road reopened shortly after 1:45pm.
The force has thanked drivers for their patience and is now calling for witnesses to come forward.
A spokesperson said: "If you witnessed the incident or have dashcam footage which could help our investigation, call 101 and quote reference 5223295665.
"Alternatively, contact Crimestoppers anonymously via its website or on 0800 555111."
