A fire on a double decker bus closed the A45 in Northampton in both directions this morning as crews tackled the blaze.
Emergency services were called to the fire at 9.21am between Riverside and Barnes Meadow. Two fire crews attended, along with a water carrier.
No further details are available at this time.
Northamptonshire Police, tweeting via @Northants_RPU, said the road had been closed while fire crewes were dealing with the blaze and urged drivers to avoid the area.
At 10am, police said the eastbound carriageway had reopened but the westbound carriageway was due to remain closed until at least 11am due to a large fuel spillage across the road.
