Emergency services rushed to the scene just before the slip-road at Junction 17 eastbound at around 10pm on Sunday.
Multiple vehicles were involved in the incident, with one overturning and catching fire.
One person was freed from a burning vehicle as members of the public sprung into action before emergency services arrived.

Ambulances, fire engines and as many as 10 police vehicles were later on hand to deal with the incident.
Plumes of smoke were seen soaring into the night’s sky as traffic in both directions was brought to a standstill.
Some motorists were also seen opening their car doors to assess the situation.
A helicopter can be seen on the tarmac as emergency services pulled out all the stops to respond to the incident.
One casualty was taken to hospital by land ambulance.
The person is not believed to have sustained life-changing or life-threatening injuries.
