The service station road in Buckinghamshire has reopened after a double decker lorry fire closed the road in both directions.
Emergency services were called to the northbound entry to Newport Pagnell services carriageway, at about 10pm on Tuesday.
Police confirmed the incident wasn't suspicious "and no one is hurt".
The entry to the services was shut and drivers were asked to avoid the road.
The motorway itself remains open.
Buckinghamshire Fire and Rescue Service sent five crews from Olney, Broughton, Newport Pagnell, West Ashland and Towcester.
The firefighters used two sets of breathing apparatus, two hose reel jets, two main jets and an environmental grab pack.
