Fans travelling to London for the weekend's FA Cup semi-finals have been urged to steer clear of the M1 highway.
The road in between junctions one and four have been closed for Saturday and Sunday by the Highways Agency because of a warehouse fire in Mill Hill.
This could lead to chaos tomorrow as supporters of both Manchester United and Manchester City make the trek south with Bolton and Stoke City fans following the next day.
With the London marathon also being held in town this Sunday, this untimely scrapheap fire could cause plenty of problems on a busier than usual weekend in the nation's capital.
