Firefighters are still tackling a barn blaze near Thame which closed the A148 for four hours last night.
One fire crew is still on the scene at Abbey Farm in North Weston.
The blaze started around 5.20pm last night.
A spokeswoman from the fire service said the barn contained 'a lot' of hay.
She said: “We are still working on it, there are still hot spots and heavy smoke.”
Oxfordshire Fire and Rescue Service closed the A148 in both directions just before 7pm last night so they could tackle the flames.
Smoke was also drifting across the highway making it hazardous for motorists to drive.
